This patch makes use of cros_ec_cmd_xfer_status() instead of cros_ec_cmd_xfer(). In this case there is no advantage of doing this apart from that we want to make cros_ec_cmd_xfer() a private function for the EC protocol and let people only use the cros_ec_cmd_xfer_status() to return Linux standard error codes.
