wifi: mt76: mt7915: fix incorrect tx path number configuration

Browse Source 
For a variant of mt7916, it supports up to 3 tx/rx paths but only 2
spatial streams. This implies that it has one more path to support
beamform. The correct tx/rx path number shall be configured to make sure
beamform works properly.
