Stefan Hajnoczi a4eef0711b vhost-user-blk-pci: default num_queues to -smp N 
Automatically size the number of request virtqueues to match the number
of vCPUs.  This ensures that completion interrupts are handled on the
same vCPU that submitted the request.  No IPI is necessary to complete
an I/O request and performance is improved.  The maximum number of MSI-X
vectors and virtqueues limit are respected.
