Subject: [PATCH v3 09/12] kasan/x86: call kasan_init_generic in kasan_init

Call kasan_init_generic() which handles Generic KASAN initialization
and prints the banner. Since x86 doesn't select ARCH_DEFER_KASAN,
kasan_enable() will be a no-op, and kasan_enabled() will return
IS_ENABLED(CONFIG_KASAN) for optimal compile-time behavior.

Closes: https://bugzilla.kernel.org/show_bug.cgi?id=217049
