NFSv4: Dont list system.nfs4_acl for filesystems that don't support it.

Thanks to Frank Filz for pointing out that we list system.nfs4_acl extended attribute even on filesystems where we don't actually support nfs4_acl. This is inconsistent with the e.g. ext3 POSIX ACL behaviour, and seems to annoy cp. Signed-off-by: J. Bruce Fields <[email protected]> Signed-off-by: Trond Myklebust <[email protected]>
