pNFS/NFSv4: Fix a layout segment leak in pnfs_layout_process()
[ Upstream commit 814b84971388cd5fb182f2e914265b3827758455 ]
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: 9888d837f3
("pNFS: Force a retry of LAYOUTGET if the stateid doesn't match our cache")
