wifi: mt76: mt7927: set band index for sniffer mode

Browse Source 
Use the active channel context to select the SNIFFER command band index on
MT7927, and fall back to the PHY chandef when no channel context is
available.

Also pass the same band index to the sniffer channel configuration. This
keeps monitor setup on the correct band, especially when multiple PHY band
contexts are present.
