Currently there are two copies of some resource freeing code, turn it into
a function and call it.

We need to settle on the kind of interrupts we'll be using, a choice that
also impacts the number of queues, before registering and making visible
the net_devices.  Move the relevant code up a bit.

ethtool_op_set_flags() does not check for unsupported flags, and has
no way of doing so.  This means it is not suitable for use as a
default implementation of ethtool_ops::set_flags.

Add a 'supported' parameter specifying the flags that the driver and
hardware support, validate the requested flags against this, and
change all current callers to pass this parameter.

Change some other trivial implementations of ethtool_ops::set_flags to
call ethtool_op_set_flags().

The PF driver needs to remain alert while its ports are down to service
requests or errors from virtual functions or FW so keep interrupts and
queues available when the ports are brought down.  The change makes
open_device_map unnecessary so remove it.
