hw/block/nvme: add max_ioqpairs device parameter
The num_queues device paramater has a slightly confusing meaning because
it accounts for the admin queue pair which is not really optional.
Secondly, it is really a maximum value of queues allowed.
Add a new max_ioqpairs parameter that only accounts for I/O queue pairs,
but keep num_queues for compatibility.
