Ondřej Surý f8b7188a42 Detach the views in zone_shutdown(), not in zone_free() ...

The .view (and possibly .prev_view) would be kept attached to the
removed zone until the zone is fully removed from the memory in
zone_free().  If this process is delayed because server is busy
something else like doing constant `rndc reconfig`, it could take
seconds to detach the view, possibly keeping multiple dead views in the
memory.  This could quickly lead to a massive memory bloat.

Release the views early in the zone_shutdown() call, and don't wait
until the zone is freed.
