qcacld-3.0: Update MCS index appropriately

qcacld-2.0 to qcacld-3.0 propagation

When AP is configured with MCS index less than 4(43Mbps) then Host
reports invalid MCS Index to upper-layer, leading to display invalid
link speed on GUI.
Updating MCS index with valid value and thereby updating correct MCS
index to upper-layer
