platform/chrome: cros_ec_proto: Convert EC error codes to Linux error codes
The EC reports a variety of error codes. Most of those, with the exception
of EC_RES_INVALID_VERSION, are converted to -EPROTO. As result, the actual
error code gets lost. In cros_ec_cmd_xfer_status(), convert all EC errors
to Linux error codes to report a more meaningful error to the caller to aid
debugging.
