Always check for ENODATA with ENOATTR
Linux defines ENODATA and ENOATTR with the same value, which means that code can miss on on the two without breaking. FreeBSD does not have ENODATA and GlusterFS defines it as ENOATTR just like Linux does. On NetBSD, ENODATA != ENOATTR, hence we need to check for both values to get portable behavior.
