Change the behavior of ao2_link().  Previously, in inherited a reference.
Now, it automatically increases the reference count to reflect the reference
that is now held by the container.

This was done to be more consistent with ao2_unlink(), which automatically
releases the reference held by the container.  It also makes it so it is
no longer possible for a pointer to be invalid after ao2_link() returns.
