pNFS: Clear the layout metadata if the server changed the layout stateid
If the server changed the layout stateid's "other" field, then we should treat the old layout as being completely gone. In that case, we want to clear the metadata such as scheduled layoutreturns. Do this by calling pnfs_mark_layout_stateid_invalid(). Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
