Lorenzo Bianconi 428604fb11 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🅱️c:d::/64 dev em1
- ip -6 route show
  a🅱️c:d::/64 dev em1 metric 1024 pref medium

Fix it checking disable_ipv6 value in ip6_route_info_create routine
