Michael S. Tsirkin 57962c47ce vhost: validate vhost_get_vq_desc return value 
[ Upstream commit a39ee449f96a2cd44ce056d8a0a112211a9b1a1f ]

vhost fails to validate negative error code
from vhost_get_vq_desc causing
a crash: we are using -EFAULT which is 0xfffffff2
as vector size, which exceeds the allocated size.

The code in question was introduced in commit
8dd014adfe
    vhost-net: mergeable buffers support
