smbd: Fix a leases.tdb record leak

smbd: Fix a leases.tdb record leak

If we set e->stale=true in the share_mode_forall_entries() callback,
the share entry will be removed directly. Thus further down
share_mode_forall_leases() won't find anything anymore. Only find
possibly still connected entries in the first walk, and then remove
the share_entries.tdb record straight away after the leases and
brlocks have been removed.
