Commit 8634b51f (locks: convert lease handling to file_lock_context) introduced a regression in the handling of lease upgrade/downgrades. In the event that we already have a lease on a file and are going to either upgrade or downgrade it, we skip doing any list insertion or deletion and simply re-call lm_setup on the existing lease. As of commit 8634b51f however, we end up calling lm_setup on the lease that was passed in, instead of on the existing lease. This causes us to leak the fasync_struct that was allocated in the event that there was not already an existing one (as it always appeared that there wasn't one).
