[RFC-v2 6/6] virtio-scsi: Fix incorrect VirtIOSCSI->cmd_vqs[0] definition

From: Nicholas Bellinger <redacted>

This patch fixes bug in the definition of VirtIOSCSI->cmd_vqs[0],
where the return of virtio_add_queue() in virtio_scsi_init() ends up
overwriting past the end of ->cmd_vqs[0].

Since virtio_scsi currently assumes a single vqs for data, this patch
simply changes ->cmd_vqs[1] to handle the single VirtQueue.
