Subject: [PATCH v2] trace: events: fix error directive in argument list

This patch fixes below spare errors.

Sparse error:
make C=2 CF=-D__CHECK_ENDIAN__ M=net/core
./include/trace/events/neigh.h:73:1: error: directive in argument list
./include/trace/events/neigh.h:78:1: error: directive in argument list
./include/trace/events/neigh.h:150:1: error: directive in argument list
./include/trace/events/neigh.h:155:1: error: directive in argument list

Changes below two lines to signle line to avoid sparse error
               if (n->tbl->family == AF_INET6) {
to if (IS_ENABLED(CONFIG_IPV6) && n->tbl->family == AF_INET6)
