vhost: vringh: Modify the return value check
[ Upstream commit 82a8d0fda55b35361ee7f35b54fa2b66d7847d2b ]
The return value of copy_from_iter and copy_to_iter can't be negative,
check whether the copied lengths are equal.
Fixes: 309bba39c945 ("vringh: iterate on iotlb_translate to handle large translations")
