[ Upstream commit8889676cd6] sd_read_block_limits_ext() currently assumes that vpd->len excludes the size of the page header. However, vpd->len describes the size of the entire VPD page, therefore the sanity check is incorrect. In practice this is not really a problem since we don't attach VPD pages unless they actually report data trailing the header. But fix the length check regardless. This issue was identified by Wukong-Agent (formerly Tencent Woodpecker), a code security AI agent, through static code analysis.
