qcacld-3.0: Update MCS set on add_sta in LFR2 scenario

Browse Source 
In LFR2 scenario, STA roams to IOT AP with which max nss
capability is advertised because ini configured vendor OUI
and data for max nss is found in AP's beacons or probe
responses. On receiving association response with reduced
nss, nss is not updated as part of add_sta. This is resulting
in incorrect nss to be sent in peer_assoc command.

Fix is to update MCS set so that appropriate nss is sent in
peer_assoc command.
