wifi: mt76: mt7915: Fix chainmask calculation on mt7915 DBDC
mt7915 does not have a per-band number of chains unlike the other chips, it only has a total number of chains. Yet the current code would consider the total number as a per-band number. For example, it would report that a 2x2 + 2x2 DBDC card have 4 chains on each band and set chainmask to 0b1111 for the first interface and 0b11110000 for the second.
