kunit: fix kunit_test_init_section_suites(...)

Looks like kunit_test_init_section_suites(...) was messed up in a merge
conflict. This fixes it.

kunit_test_init_section_suites(...) was not updated to avoid the extra
level of indirection when .kunit_test_suites was flattened. Given no-one
was actively using it, this went unnoticed for a long period of time.

Fixes: e5857d39 ("kunit: flatten kunit_suite*** to kunit_suite** in .kunit_test_suites")
