wifi: mt76: mt7921: fix uninitialized variable warning

Browse Source 
Move the initialization of 'dev' before the error path that uses it.
This fixes the compiler warning:
  drivers/net/wireless/mediatek/mt76/mt7921/pci.c:347:6: warning:
  variable 'dev' is used uninitialized whenever 'if' condition is true
