Guillaume Nault 869f1704f1 Revert "ipv6: Honor all IPv6 PIO Valid Lifetime values" ...

[ Upstream commit 36268983e90316b37000a005642af42234dabb36 ]

This reverts commit b75326c201.

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.

Fixes: b75326c201 ("ipv6: Honor all IPv6 PIO Valid Lifetime values")
