Revert "ipv6: Honor all IPv6 PIO Valid Lifetime values"
This reverts commit b75326c2. This commit breaks Linux compatibility with USGv6 tests. The RFC this commit was based on is actually an expired draft: no published RFC currently allows the new behaviour it introduced. Without full IETF endorsement, the flash renumbering scenario this patch was supposed to enable is never going to work, as other IPv6 equipements on the same LAN will keep the 2 hours limit.
