odhcp6c: fix safe interval processing to follow RFC 4862

This resolves an issue occuring in combination with Fritz! upstream
routers that send old prefixes with a valid time of zero for a long
time. Before this change, they were with each received RA extended
to two hours if the prefix was already known before.
