From 7e849dd9cf37 ("nvme-pci: don't share queue maps"), the mapping
table won't be initialized actually if map->nr_queues is zero, so
we can't use blk_mq_map_queue_type() to retrieve hctx any more.
This way still may cause broken mapping, fix it by skipping zero-queues
maps in blk_mq_map_swqueue().Applied, thanks. -- Jens Axboe
