qcacld-3.0: Update VHT IE with highest supported LGI rate 

Currently, the Rx/Tx highest Long GI data rate field in
the  VHT IE is filled with short GI data rate. Therefore,
change the highest supported data rate back to LGI data
rate.

Allow the short GI rate to be filled as the highest supported
rate in the wiphy if short GI is enabled.
