pNFS: Mark layout for return if return-on-close was not sent

Browse Source 
If the layout return-on-close failed because the layoutreturn was never
sent, then we should mark the layout for return again.

Fixes: 9c47b18cf7 ("pNFS: Ensure we do clear the return-on-close layout stateid on fatal errors")
