There are a small, bounded set of placement_ids that the socket layer
will ever encounter, and they remain valid for the lifetime of the
program. The association between a poll group and a placement_id is now
correctly broken when the reference count drops to 0 (in response to
sock_map_release calls), so do not free the entry when the poll group is
destroyed so that it may be reused again.
