Jason Wang 38d315f14f vhost: correctly check the return value of translate_desc() in log_used() ...

[ Upstream commit 816db76635 ]

When fail, translate_desc() returns negative value, otherwise the
number of iovs. So we should fail when the return value is negative
instead of a blindly check against zero.
