NSM: Release nsmhandle in nlm_destroy_host
The nsm_handle's reference count is bumped in nlm_lookup_host(). It
should be decremented in nlm_destroy_host() to make it easier to see
the balance of these two operations.
Move the nsm_release() call to fs/lockd/host.c.
The h_nsmhandle pointer is set in nlm_lookup_host(), and never cleared.
The nlm_destroy_host() function is never called for the same nlm_host
twice, so h_nsmhandle won't ever be NULL when nsm_unmonitor() is
called.
All references to the nlm_host are gone before it is freed. We can
skip making h_nsmhandle NULL just before the nlm_host is deallocated.
It's also likely we can remove the h_nsmhandle NULL check in
nlmsvc_is_client() as well, but we can do that later when rearchitect-
ing the nlm_host cache.
