mempool_alloc() allocates an element for mbp from a specific memory pool.
When some error occurs, we should free this memory pool with
mempool_free(). But when cbfn != NULL, the function returns 0 without
freeing the mbp, which will lead to a memory leak.
We can fix it by calling mempool_free() when the cbfn != NULL.
