In preparation for making the kmalloc family of allocators type aware, we need to make sure that the returned type from the allocation matches the type of the variable being assigned. (Before, the allocator would always return "void *", which can be implicitly cast to any pointer type.) The assigned type is "struct idxd_wq **", but the returned type will be "struct wq **". These are the same size allocation (pointer sized), but the types don't match. Adjust the allocation type to match the assignment.
