I'd prefer to just add the two fields direct to struct request_queue
instead of the container structure.

I don't think this is going to compile without CONFIG_BLK_DEV_ZONED,
we'd either need two versions of it, or just always add nr_zones to
the request queue.
With nr_zones always present we could then remove the first check,
too as it would always be initialized to zero.
