qcacmn: populate NSS value and Translate MCS value for HT

Browse Source 
This change will resolve displaying NSS value
in stats in case of HT. And also it will give
proper NSS value to calculate rate value. Modify MCS
value to match with Tx stats from firmware.

Also retain original MCS value to use in radiotap code
for HT case.
