This patch adds RX workqueue support for USB interfaces.
Currently rx_pending is applicable for cmd/events and Rx
data in USB interface. Let's use it only for Rx data.

completed reconfiguring after resume (e.g. in order

Rename restart_complete() to a more-generic reconfig_complete(),
and add a new enum to indicate the reconfiguration type.

Disconnect flow may be invoked either from upper layer request,
or from event reported by the firmware.

In case of firmware event, driver need to release resources for the station but
not send another disconnect WMI command.

In case of upper layer request, WMI_DISCONNECT_STA_CMDID command need to
be issued for the firmware to perform disconnect on the MAC layer. Eventually,
event is expected to confirm MAC disconnect, but it is better to not wait for
firmware event and release station resources immediately. FW may fail to
report disconnect for various reasons, so one could not rely on event always reported.

Introduce parameter to distinguish 2 cases above to prevent double WMI command
issuing.

When interface is down, recovery flow should not be attempted.
Next ndo_open() will trigger target reset, that is FW recovery.

Doing recovery while interface is down cause internal "up", leaving
internal driver state in conflict with network stack. Then, when network
stack will call ndo_open(), kernel oops will be triggered.
