scsi: scsi_debug: Support host tagset
When host_max_queue is set (> 0), set the Scsi_Host.host_tagset such that
blk-mq will use a hostwide tagset over all SCSI host submission queues.
This means that we may expose all submission queues and always use the hwq
chosen by blk-mq.
And since if sdebug_host_max_queue is set, sdebug_max_queue is fixed to the
same value, we can simplify how sdebug_driver_template.can_queue is set.
