[shill] Un-do a few usages of ref-counted pointers where they cause cycles
Giving an Adaptor a ref-counted pointer to the object for which it is an adaptor
causes an ownership cycle that leads to memory leaks.
In lieu of trying to create some more formal structure, just rely on the fact
that a Device/Service/Manager creates and owns its Adaptor and give a bare
pointer to the Adaptor when it is created.
