4.14-stable review patch. If anyone has any objections, please let me know.

From: Dominique Martinet asmadeus@codewreck.org
[ Upstream commit 4a73edab69d3a6623f03817fe950a2d9585f80e4 ]
Similarly to the previous patch: offs can be used in handle_rerrors without initializing on small payloads; in this case handle_rerrors will not use it because of the size check, but it doesn't hurt to make sure it is zero to please scan-build.
This fixes the following warning: net/9p/trans_virtio.c:539:3: warning: 3rd function call argument is an uninitialized value [core.CallAndMessage] handle_rerror(req, in_hdr_len, offs, in_pages); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
