qcacld-3.0: Set 2.4G NSS to 1 for NDI if antenna sharing present

If antenna sharing is supported, target must not include 2x2
rates in HT IE for NAN Datapath related frames. Therefore set
2.4GHz band NSS to 1x1 in NDI vdev NSS config parameters.

Set 2.4GHz NSS to 1x1 for NDI if antenna sharing is supported.
