vhost-user-scsi: prevent using uninitialized vqs
Of the 3 virtqueues, seabios only sets cmd, leaving ctrl
and event without a physical address. This can cause
vhost_verify_ring_part_mapping to return ENOMEM, causing
the following logs:
qemu-system-x86_64: Unable to map available ring for ring 0
qemu-system-x86_64: Verify ring failure on region 0
The qemu commit e6cc11d64fc998c11a4dfcde8fda3fc33a74d844
has already resolved the issue for vhost scsi devices but
the fix was never applied to vhost-user scsi devices.
