vhost/scsi: silence uninitialized variable warning
This is to silence an uninitialized variable warning in debug output.
The problem is this line:
pr_debug("vhost_get_vq_desc: head: %d, out: %u in: %u\n",
head, out, in);
If "head == vq->num" is true on the first iteration then "out" and "in"
aren't initialized. We handle that a few lines after the printk. I was
tempted to just delete the pr_debug() but I decided to just initialize
them to zero instead.
Also checkpatch.pl complains if variables are declared as just
"unsigned" without the "int".
