qcacld-3.0: Update OFDM rates only if oper freq is 5GHz

Browse source 
In PE session, host updates supported rates from beacon IE stored
in BSS descriptor. If OFDM rates are present in beacon while
operating frequency is not from 5GHz band, host copies them into
PE session's supported rated.
Hence add a check to avoid adding OFDM rates while operating
frequency is not 5GHz.
