Guenter reported an boot hang issue on HPPA after we default to 0 poll queues. We have two issues in the queue count calculations: 1) We don't separate the poll queues from the read/write queues. This is important, since the former doesn't need interrupts. 2) The adjust logic is broken. Adjust the poll queue count before doing nvme_calc_io_queues(). The poll queue count is only limited by the IO queue count we were able to get from the controller, not failures in the IRQ allocation loop. This leaves nvme_calc_io_queues() just adjusting the read/write queue map.
