net: ipv4: avoid unused variable warning for sysctl

Browse source

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.

Fixes: c7272c2f12 ("net: ipv4: don't allow setting net.ipv4.route.min_pmtu below 68")
