From: Jiale Yao <jiale.yao at example.com>

The mt7996 beamforming configuration converts a peer maximum NSS to a
zero-based column count.  A peer may report no receive streams for a
VHT, HE, or EHT MCS range.  Decrementing that zero value underflows and
can send an invalid beamforming configuration to firmware.

Patch 1 fixes the shared VHT and HE MCS-map conversion.  Patch 2 fixes
the corresponding EHT conversions for 80, 160, and 320 MHz operation.

The series was checked with scripts/checkpatch.pl, and each patch was
checked for application against the common base.
