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.

Set ctx->msgbuf.data to NULL during the call. If ctx->msgbuf is needed
during the call, a new buffer will be allocated. If not,
ctx->msgbuf.data is restored to the previous value afterwards

This allows sharing a policy array across methods, but masking out
unused entries for individual methods.

When process unsubscribes then remove callback is called. But it
can be NULL if not defined, so we should check it before we call it.
