Michael S. Tsirkin a2a366ebac vhost: validate vhost_get_vq_desc return value ...

[ Upstream commit a39ee449f9 ]

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

    vhost-net: mergeable buffers support
