[PATCH 1/2] ath10k: change beamformee VHT STS capability

[Michal Kazior]

From: Bartosz Markowski <bartosz.markowski at tieto.com>

All beamformee supporting chips have the ability to support
VHT NDP in up to 4 STSs. Change the published beamformee
STS cap accordingly to 3 as it should be Nsts-1.

This makes it possible to actually make full use
of. e.g. a 4SS MU-MIMO capable AP.
