[ Upstream commit 4f8be1f53bf615102d103c0509ffa9596f65b718 ]
The NFSv4 protocol doesn't have any notion of reomoving an attribute, so
removexattr(path,"system.nfs4_acl") doesn't make sense.
There's no documented return value. Arguably it could be EOPNOTSUPP but
I'm a little worried an application might take that to mean that we
don't support ACLs or xattrs. How about EINVAL?
