qcacld-3.0: Update dot11 mode correctly

In case of sap big data logging, it is assumed that legacy
dot11 mode is always supported, if the connection is done
in 11ax and if station does not shares the ht and vht info
in that case legacy dot11 mode should not be updated as it
is possible that sta is only 11ax supported.
