NFSv4: Retry LOCK on OLD_STATEID during delegation return

[ Upstream commit f5ea16137a3fa2858620dc9084466491c128535f ]

There's a small window where a LOCK sent during a delegation return can
race with another OPEN on client, but the open stateid has not yet been
updated.  In this case, the client doesn't handle the OLD_STATEID error
from the server and will lose this lock, emitting:
"NFS: nfs4_handle_delegation_recall_error: unhandled error -10024".

Fix this by sending the task through the nfs4 error handling in
nfs4_lock_done() when we may have to reconcile our stateid with what the
server believes it to be.  For this case, the result is a retry of the
LOCK operation with the updated stateid.
