pNFS/NFSv4: Fix a layout segment leak in pnfs_layout_process()

If the server returns a new stateid that does not match the one in our
cache, then pnfs_layout_process() will leak the layout segments returned
by pnfs_mark_layout_stateid_invalid().

Fixes: 9888d837 ("pNFS: Force a retry of LAYOUTGET if the stateid doesn't match our cache")
