Trond Myklebust 1ba04394e0 NFSv4: Fix a potential state reclaim deadlock
If the server reboots while we are engaged in a delegation return, and
there is a pNFS layout with return-on-close set, then the current code
can end up deadlocking in pnfs_roc() when nfs_inode_set_delegation()
tries to return the old delegation.
Now that delegreturn actually uses its own copy of the stateid, it
should be safe to just always update the delegation stateid in place.

Fixes: 078000d02d ("pNFS: We want return-on-close to complete when evicting the inode")
