[PATCH 1/2] wifi: mt76: mt7927: set band index for sniffer mode

[Devin Wittmayer]

Tested on a real MT7927 (Filogic 380, PCIe). Two monitors on different
bands capture at the same time with the series, and drop back onto one
band without it.

I tried each patch on its own too. [1/2] by itself still collapses both
monitors onto one channel. With [2/2] they stay apart, but then one of
them stops capturing, so it looks like both are needed.

Single-band monitor and a normal station connection were both fine.
