We shouldn't put back the device into fw own state after wifi reset at
driver unbind stage to fix the following error because that is not the
consistent state the current driver bind stage expects.
localhost ~ # echo 0000:01:00.0 > /sys/bus/pci/drivers/mt7921e/unbind
localhost ~ # echo 0000:01:00.0 > /sys/bus/pci/drivers/mt7921e/bind
