If we cannot grab the inode or superblock, then we cannot pin the layout header, and so we cannot send a layoutreturn as part of an async delegreturn call. In this case, we currently end up sending an extra layoutreturn after the delegreturn. Since the layout was implicitly returned by the delegreturn, that just gets a BAD_STATEID. The fix is to simply complete the return-on-close immediately.
