py/objdeque: Fix buffer overflow in deque_subscr.
In `deque_subscr()`, if `index_val` equals `self->alloc`, the index
correction `index_val -= self->alloc` does not execute, leading to an
out-of-bounds access in `self->items[index_val]`.
The fix in this commit ensures that the index correction is applied
whenever `index_val >= self->alloc`, preventing access beyond the allocated
buffer size.
