qcacld-3.0: Fix sap started on unsupported channel

In wlan_hdd_validate_operation_channel, "status" is override
to QDF_STATUS_SUCCESS after "ucfg_mlme_get_sap_allow_all_channels"
call. Reset "status" to QDF_STATUS_E_INVAL before checking
with supported channel list, otherwise QDF_STATUS_SUCCESS
will be returned for unsupported channel case.
