qcacld-3.0: Fix STA sending SMPS force mode when connected to 1x1 AP

qcacld-2.0 to qcacld-3.0 propagation

Peer supported NSS should be updated based on the presence of HT
and VHT capabilities in the beacon/probe response IE from the AP.
Also, update session supported NSS during reassociation. Otherwise,
station will end up sending SMPS action frames to AP which only
supports 1x1 mode.
