ipv6: do not set routes if disable_ipv6 has been enabled
Do not allow setting ipv6 routes from userspace if disable_ipv6 has been
enabled. The issue can be triggered using the following reproducer:
- sysctl net.ipv6.conf.all.disable_ipv6=1
- ip -6 route add a:b:c:d::/64 dev em1
- ip -6 route show
a:b:c:d::/64 dev em1 metric 1024 pref medium
Fix it checking disable_ipv6 value in ip6_route_info_create routine
