Daniel Wagner 0a50ed0574 virtio: blk/scsi: use block layer helpers to calculate num of queues 
The calculation of the upper limit for queues does not depend solely on
the number of possible CPUs; for example, the isolcpus kernel
command-line option must also be considered.

To account for this, the block layer provides a helper function to
retrieve the maximum number of queues. Use it to set an appropriate
upper queue number limit.
