Solve the conflict in main.c early on as there will be a lot more mt76 patches
in the queue.

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
