qcacld-3.0: Remove LTE ant sharing dependency on HT connection's NSS

Browse source 
While DUT is in SAP or GO mode, due to LTE antenna sharing mechanism,
DUT is associating in 2x1 chains to HT clients.

As per new requirement, remove dependency of number of chains on antenna
sharing. If HT client supports 2 chains, and due to DBS/LTE antenna
sharing SAP/GO drops down a chain then rate adaptation at peer takes
care of dropping down chains at peer side
