NFSv4: Sanity check the server reply in _nfs4_server_capabilities
We don't want to be setting capabilities and/or requesting attributes that are not appropriate for the NFSv4 minor version. - Ensure that we clear the NFS_CAP_SECURITY_LABEL capability when appropriate - Ensure that we limit the attribute bitmasks to the mounted_on_fileid attribute and less for NFSv4.0 - Ensure that we limit the attribute bitmasks to suppattr_exclcreat and less for NFSv4.1 - Ensure that we limit it to change_sec_label or less for NFSv4.2 Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
