[PATCH v3 03/32] selftests: harness: Ignore unused variant argument warning

[Thomas Weißschuh]

For tests without fixtures the variant argument is unused.
This is intentional, prevent to compiler from complaining.

Example warning:

    harness-selftest.c: In function 'wrapper_standalone_pass':
    ../kselftest_harness.h:181:52: error: unused parameter 'variant' 
[-Werror=unused-parameter]
      181 |                 struct __fixture_variant_metadata *variant) \
          |                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~
    ../kselftest_harness.h:156:25: note: in expansion of macro '__TEST_IMPL'
      156 | #define TEST(test_name) __TEST_IMPL(test_name, -1)
          |                         ^~~~~~~~~~~
    harness-selftest.c:15:1: note: in expansion of macro 'TEST'
       15 | TEST(standalone_pass) {
          | ^~~~
