vhost-user-scsi: add missing virtqueue_size param 



Commit 5c0919d0 [1] introduced virtqueue_size parameter
for common virtio-scsi path, without updaing the vhost-user-scsi
code. vhost-user-scsi devices right now report size 0 for each vq.

This patch introduces virtqueue_size param to vhost-user-scsi,
that can now be set by the user. However, the most importantly, it
now has a default value of 128 (same as QEMU's virtio-scsi).

allowing virtqueue size to be set.")
