We should always return from thread__new(), the constructor, with the
object with a reference count of one, so that:
struct thread *thread = thread__new();
thread__put(thread);
Will call thread__delete().
If any reference is made to that 'thread' variable, it better use
thread__get(thread) to hold a reference.
We were returning with thread->refcnt set to zero, fix it and some cases
where thread__delete() was being called, which were not a problem
because just one reference was being used, now that we set it to 1, use
thread__put() instead.
