wifi: iwlwifi: validate the channels received in iwl_mcc_update_resp_v*

Browse Source 
Check with IWL_FW_CHECK that the FW doesn't send a channel that we don't
support. Otherwise, the center frequency will be 0, leading to a
warning since is_valid_reg_rule will return false, of course.
Although the warning is verbose enough, the IWL_FW_CHECK will spare some
of the debug.
