NFS: Attempt mount with default sec flavor first
nfs4_lookup_root() is already configured to use either RPC_AUTH_UNIX or a user specified flavor (through -o sec=<whatever>). We should use this flavor first, and only attempt negotiation if it fails with -EPERM. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
