[SRU][OEM-5.13/U] Fix firmware reload failure of MT7921

[AaronMa]

SRU justification:

[Impact]
MT7921 is supported on 5.13 kernel, mt76 driver failed to work when reboot.
SRUed for 5.13+ kernel only.

[Fix]
MT7921 needs both driver and firmware, firmware is SRUed.
When reboot, the firmware is already reloaded, driver probe breaks.
Continue to probe if firmware status is OK.

[Test]
Verified on hardware, After reboot system wifi works fine.

[Where problems could occur]
The MT7921 wifi may not work.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
