qcacld-3.0: Fill rate and bw info for HT/VHT frames in monitor mode

Browse source 
In monitor mode, while filling the radiotap header, rate and bw
info for HT and VHT frames was not filled correctly due to which
packets in tcpdump are showing incorrect rates and bw for HT/VHT
frames.

Fill rate and bw info for HT/VHT frames correctly in monitor mode.
