Subject: [PATCH 1/2] net: ipv6: af_inet6: Fix warning when CONFIG_SYSCTL=n

From: Fabio Estevam <fabio.estevam@...escale.com>

When CONFIG_SYSCTL=n the following build warning happens:

net/ipv6/af_inet6.c:710:13: warning: 'ipv6_packet_cleanup' defined but not used [-Wunused-function]

ipv6_packet_cleanup() is only used when CONFIG_SYSCTL=y, so protect its 
definition with an'ifdef CONFIG_SYSCTL'.
