qcacld-3.0: Initiate connection in with 2x2 even if antenna is shared by LTE

Browse Source 
If STA LTE antenna sharing is enabled sometime STA connect with NSS1
even AP is broadcasting NSS 2 capability if the chainmask received in
vdev start resp indicate 1x1. But the connection should be 2x2 and
after association the chainmask mgr will drop it down to 1x1.

Thus initiate connection in with 2x2 even if antenna is shared by LTE
during connection initiation.
