Update icmp6_redirect_timeout_q when changing net.inet6.icmp6.redirtimeout
We have to update icmp6_redirect_timeout_q as well as icmp6_redirtimeout
when changing net.inet6.icmp6.redirtimeout via sysctl. The updating logic
is copied from sysctl_net_inet_icmp_redirtimeout.
This change is from s-yamaguchi@IIJ (with KNF by ozaki-r) and fixes
PR kern/50240.
