nfsd4: clean up open owners on OPEN failure
If process_open1() creates a new open owner, but the open later fails, the current code will leave the open owner around. It won't be on the close_lru list, and the client isn't expected to send a CLOSE, so it will hang around as long as the client does. Similarly, if process_open1() removes an existing open owner from the close lru, anticipating that an open owner that previously had no associated stateid's now will, but the open subsequently fails, then we'll again be left with the same leak. Fix both problems. Reported-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
