libubus: Fix deletion from context's object AVL tree when removing object
Objects are stored in the ubus context in an AVL tree. An AVL tree
node contains a pointer to a key value. For the ubus context, this
points to the id member of the object structure. In
ubus_remove_object_cb, the id member is set to zero and then after,
avl_delete is called and fails. To fix this, we call avl_delete
before setting the object id to zero.
