NFSv4.x: Drop the slot if nfs4_delegreturn_prepare waits for layoutreturn

commit 5326de9e94bedcf7366e7e7625d4deb8c1f1ca8a upstream.

If nfs4_delegreturn_prepare needs to wait for a layoutreturn to complete
then make sure we drop the sequence slot if we hold it.

Fixes: 1c5bd76d17cc ("pNFS: Enable layoutreturn operation for return-on-close")
