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

stable inclusion
from linux-4.19.169
commit 87396ce3b5059916e81b6c3456a5c2b9b7636b5f

--------------------------------

commit 67bbceed upstream.

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