qcacld-3.0: Validate freq against regulatory list

Browse source 
When CSR issues a start BSS message, it validates the requested start
freq against the internal CSR channel list. There could be a scenario
where this list is not updated and the validation fails. Check this freq
against the regulatory channel list instead.
