kasan: rename test_kasan_module_init to kasan_test_module_init

After commit f7e01ab8 ("kasan: move tests to mm/kasan/"), the test
module file is renamed from lib/test_kasan_module.c to
mm/kasan/kasan_test_module.c, in order to keep consistent, rename
test_kasan_module_init to kasan_test_module_init.
