net: ipv6: ndisc: Fix warning when CONFIG_SYSCTL=n
net: ipv6: ndisc: Fix warning when CONFIG_SYSCTL=n

When CONFIG_SYSCTL=n the following build warning happens:

net/ipv6/ndisc.c:1730:1: warning: label 'out' defined but not used [-Wunused-label]

The 'out' label is only used when CONFIG_SYSCTL=y, so move it inside the
'ifdef CONFIG_SYSCTL' block.
