From: Trond Myklebust <[email protected]>
If the layout return-on-close failed because the layoutreturn was never
sent, then we should mark the layout for return again.
Fixes: 9c47b18cf722 ("pNFS: Ensure we do clear the return-on-close layout stateid on fatal errors")

If the inode is being evicted, it should be safe to run return-on-close,
so we should do it to ensure we don't inadvertently leak layout segments.

Remove the check for whether or not the stateid is NULL, and fix up the
callers.
