qom: fix refcount of non-heap-allocated objects
The reference count for embedded objects is always one too low, because
object_initialize_with_type returns with zero references to the object.
This causes premature finalization of the object (or an assertion failure)
after calling object_ref to add an extra reference and object_unref to
remove it.
The fix is to move the initial object_ref call from object_new_with_type
to object_initialize_with_type.
