net/ipv6: Fix the RT cache flush via sysctl using a previous delay
The net.ipv6.route.flush system parameter takes a value which specifies
a delay used during the flush operation for aging exception routes. The
written value is however not used in the currently requested flush and
instead utilized only in the next one.
A problem is that ipv6_sysctl_rtcache_flush() first reads the old value
of net->ipv6.sysctl.flush_delay into a local delay variable and then
calls proc_dointvec() which actually updates the sysctl based on the
provided input.
Fix the problem by switching the order of the two operations.
Fixes: 4990509f19e8 ("[NETNS][IPV6]: Make sysctls route per namespace.")
