Subject: [PATCH 18/34] lib: checksum: hide unused expected_csum_ipv6_magic[]

From: Arnd Bergmann <arnd@...db.de>

When CONFIG_NET is disabled, an extra warning shows up for this
unused variable:

lib/checksum_kunit.c:218:18: error: 'expected_csum_ipv6_magic' defined but not used [-Werror=unused-const-variable=]

Hide it under the same #ifdef as the reference to it.

Fixes: f24a70106dc1 ("lib: checksum: Fix build with CONFIG_NET=n")
Signed-off-by: Arnd Bergmann <arnd@...db.de>
