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=]
Replace the #ifdef with an IS_ENABLED() check that makes the compiler's
dead-code-elimination take care of the link failure.
Fixes: f24a70106d ("lib: checksum: Fix build with CONFIG_NET=n")
