block: Add rdma affinity based queue mapping helper Like pci and virtio, we add a rdma helper for affinity spreading. This achieves optimal mq affinity assignments according to the underlying rdma device affinity maps.

block: Change the return type of blk_mq_map_queues() into void Since blk_mq_map_queues() and the .map_queues() callbacks always return 0, change their return type into void.
