NLM: Fix a memory leak in nlmsvc_testlock
The recent fix for a circular lock dependency unfortunately introduced a potential memory leak in the event where the call to nlmsvc_lookup_host fails for some reason. Thanks to Roel Kluin for spotting this. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
