Subject: [PATCH] libmultipath: actually truncate too-large vpd page.
When multipath notices that the vpd page is too large, it needs to
actually truncate it. Also, whe calling parse_vpd_pg83() with a possibly
truncated page, multipath needs to check that it actually has a whole
vpd entry, before trying to use it.
