qcacld-3.0: Initialize vdev_nss in psession when roaming

Propagation from qcacld-2.0 to qcacld-3.0.

When Dut is configured as 1*1, after roaming to 2*2 AP,
the linkspeed is not right, it will display 144Mpbs rather
than 72Mbps. Because it uses wrong peer_nss and
peer_rate_caps in WMI_PEER_ASSOC_CMDID.
