net/ipv4/tcp_metrics.c: In function '__tcp_get_metrics_tw':
net/ipv4/tcp_metrics.c:252:3: error: implicit declaration of function 'inet6_twsk' [-Werror=implicit-function-declaration]
net/ipv4/tcp_metrics.c:252:7: warning: assignment makes pointer from integer without a cast [enabled by default]
net/ipv4/tcp_metrics.c:253:41: error: dereferencing pointer to incomplete type

Fixed as follows:

====================
ipv6: Move ipv6 twsk accessors outside of CONFIG_IPV6 ifdefs.

Fixes build when ipv6 is disabled.
