qcacld-3.0: Check channel bw valid in pre vdev start

Browse source 
wlan_reg_set_channel_params_for_freq API will check the bonded
channels are valid or not. If invalid ch width is returned, that
means no suitable channel bonding in current regdomain for
requested channel frequency, then abort the vdev start request.
