commit 773daa3caf5d3f87fdb1ab43e9c1b367a38fa394 upstream.
The newly introudced ip_min_valid_pmtu variable is only used when CONFIG_SYSCTL is set:
net/ipv4/route.c:135:12: error: 'ip_min_valid_pmtu' defined but not used [-Werror=unused-variable]
This moves it to the other variables like it, to avoid the harmless warning.
