Make sure that the cmd_per_lun value placed in the host template

set to CAN_QUEUE. CAN_QUEUE is a compile time constant and is used
to dimension an array to hold queued requests. If the max_queue
driver parameter is given it is must be less than or equal to
CAN_QUEUE and if so, the host template values are adjusted.
Remove undocumented code that allowed queue_depth to exceed
CAN_QUEUE and cause stack full type errors. There is a documented
way to do that with every_nth and
echo 0x8000 > /sys/bus/pseudo/drivers/scsi_debug/opts
See: https://sg.danny.cz/sg/scsi_debug.html
Tweak some formatting, and add a suggestion to the "trim
poll_queues" warning.
