mt76x0: fix remove_interface
We wrongly use wcid_mask instead of vif_mask. This creates problems
when the interface is removed more than 8 times, for example with iw:
iw dev <devname> interface add <name> type <type>
iw dev <name> del
This caused 'ifconfig up' to fail with error:
SIOCSIFFLAGS: No space left on device
Fixes: 95e444098a7b ("mt76x0: main file")
