The current hns3_get_max_available_channels returns the total number
of queues for the device, which makes ethtool -L set the number of queues
per channel queues incorrectly, so hns3_get_max_available_channels should
return the maximum available number of queues per channel, depending on
the total number of queues allocated and the hardware configurations.

When roce is loaded before nic, the roce client will not be initialized
until nic client is initialized, but roce init flag is set before it.
Furthermore, in this case of nic initialized success and roce failed,
the nic init flag is not set, and roce init flag is not cleared.

This patch fixes it by set init flag only after the client is initialized
successfully.

The ae_algo is used by many ae_devs. It is not only belong to just a
ae_dev. Initializing ae_dev failed does not represent registering ae_algo
failed. Because the action of registering ae_algo just is adding ae_algo
to the ae_algo list and it is always is true, it make no sense to define
return type as int.

This patch changes the return type of hnae3_register_ae_algo from int to

If hclge.ko has not been inserted, the value of ret always is zero
in hnae3_register_ae_dev. If hclge.ko has been inserted, the value
of ret is zero or non zero. Different execution ways have different
results. It is confusing.

The ae_dev which is initialized failed can be reinitialized when we
remove hclge.ko and insert it again. For the case initializing client
instance, it is just like the case initializing ae_dev. The main function
of hnae3_register_ae_dev is adding the ae_dev to ad_dev list. Because
adding ae_dev is always ok, we does not need to return any in this
function.

This patch changes the return type of hnae3_register_ae_dev from int
to void.

This introduces the hclge device reset states of "requested" and
"pending" and also its handling in context to Reset Service Task.

Device gets into requested state because of any VF reset request
asserted from upper layers, for example due to watchdog timeout
expiration. Requested state would result in eventually forwarding
the VF reset request to PF which would actually reset the VF.

Device will get into pending state if:
1. VF receives the acknowledgement from PF for the VF reset
   request it originally sent to PF.
2. Reset Service Task detects that after asserting VF reset for
   certain times the data-path is not working and device then
   decides to assert full VF reset(this means also resetting the
   PCIe interface).
3. PF intimates the VF that it has undergone reset.
Pending state would result in VF to poll for hardware reset
completion status and then resetting the stack/enet layer, which
in turn means reinitializing the ring management/enet layer.

Note: we would be adding support of 3. later as a separate patch.
This decision should not affect VF reset as its event handling
is generic in nature.

HNS3 drivers enet layer, used for the ring management and stack
interaction, is common to both VF and PF. PF already supports reset
functionality to handle the network stack watchdog timeout trigger
but the existing code is not generic enough to be used to support VF
reset as well.
This patch does following:
1. Makes the existing watchdog timeout handler in enet layer generic
   i.e. suitable for both VF and PF and
2. Introduces the new reset event handler for the VF code.
3. Changes existing reset event handler of PF code to initialize the
   reset level
