sd-dhcp6: fix crash by unrefing event sources before re-adding them

In certain cases the timeouts may not have been unref'ed before they
need to be re-added. Add the appropriate unref calls to ensure we don't
register the timeout multiple times.

This fixes possible cases where timeouts are triggered multiple times
and even on destroyed DHCPv6 clients.

Fixes #10749.
