router: don't announce prefixes with valid lifetime equal to 0
Don't set prefix valid lifetime to 0 in case the preferred lifetime equals 0 and valid lifetime gets smaller than 7200. In corner cases it leads to router lifetime being set although no prefixes are announced with a valid lifetime different from 0. Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>
