Azure: net: mana: Fix MANA VF unload when hardware is unresponsive

[Tim Gardner]

SRU Justification

[Impact]

MSFT has requested to backport commit a7dfeda6fdeccab4c7c3dce9a72c4262b9530c80 ('net: mana: Fix MANA VF unload when hardware is unresponsive').

    When unloading the MANA driver, mana_dealloc_queues() waits for the MANA
    hardware to complete any inflight packets and set the pending send count
    to zero. But if the hardware has failed, mana_dealloc_queues()
    could wait forever.

[Test Plan]

Microsoft tested. Commit upstream since 6.5

[Regression Potential]

The MANA driver may not shut down correctly.
