Release the allocated channel decreasing the reference counter.

When allocating the channel use ao2_ref(-1) to release it, instead of calling
ast_free().
Also avoid freeing structures inside that channel (on error) if they will be
released by the channel destructor being called if the reference counter reachs
0.
