bpf: cleanup aux->used_maps after jit
In commit b4ce5923e780 ("bpf, x86: add new map type: instructions array")
env->used_map was copied to func[i]->aux->used_maps before jitting.
Clear these fields out after jitting such that pointer to freed memory
(env->used_maps is freed later) are not kept in a live data structure.
The reason why the copies were initially added is explained in
