NLM: Fix a memory leak in nlmsvc_testlock
changeset a6d85430424d44e946e0946bfaad607115510989 in upstream
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.
