NFS: correctly report misuse of "migration" mount option.
The current test on valid use of the "migration" mount option can never report an error as it will only do so if mnt->version !=4 && mnt->minor_version != 0 (and some other condition), but if that test would succeed, then the previous test has already gone-to out_minorversion_mismatch. So change the && to an || to get correct semantics. Signed-off-by: NeilBrown <neilb@suse.de> Acked-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
