radix-tree: Fix UBSAN warning
get_slot_offset() can be called with a NULL 'parent' argument. In this case, the calculated value will not be used, but calculating it is undefined. Rather than fixing the caller (__radix_tree_delete) to not call get_slot_offset(), make get_slot_offset() robust against being called with a NULL parent.
