NFSv4/pnfs: Return valid stateids in nfs_layout_find_inode_by_stateid()
[ Upstream commit d911c57a19551c6bef116a3b55c6b089901aacb0 ]
Make sure to test the stateid for validity so that we catch instances
where the server may have been reusing stateids in
nfs_layout_find_inode_by_stateid().
Fixes: 7b410d9ce460 ("pNFS: Delay getting the layout header in CB_LAYOUTRECALL handlers")
