(OMPI_ERR_* = OPAL_SOS_GET_ERR_CODE(ret)), since the return value could be a SOS-encoded error. The OPAL_SOS_GET_ERR_CODE() takes in a SOS error and returns back the native error code. * Since OPAL_SUCCESS is preserved by SOS, also change all calls of the form (OPAL_ERROR == ret) to (OPAL_SUCCESS != ret). We thus avoid having to decode 'ret' to get the native error code. This commit was SVN r23162.
