wifi: mt76: mt7996: use correct phy for background radar event

[ Upstream commit 9ffe0d5690ed916e09baad2cc9ee7ec65b110038 ]

If driver directly uses the band_idx reported from the radar event to
access mt76_phy array, it will get the wrong phy for background radar.
Fix this by adjusting the statement.
