lightningd: handle channel cleanups more explicitly.

Browse Source 
1. Freeing an unconfirmed channel already releases the subd, so don't
   do that explicitly.
2. Use channel->owner to transfer ownership where possible, using
   channel_set_owner() which handles all the cases.

This simplifies the code and makes it more readable, IMHO.
