Summary
wifi: mt76: do not run mt76_unregister_device() on unregistered hw
Details

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: do not run mt76unregisterdevice() on unregistered hw

Trying to probe a mt7921e pci card without firmware results in a successful probe where ieee80211registerhw hasn't been called. When removing the driver, ieee802111unregisterhw is called unconditionally leading to a kernel NULL pointer dereference. Fix the issue running mt76unregisterdevice routine just for registered hw.
