Subject: [PATCH 3/9] kasan/arm64: call kasan_init_generic in kasan_init

Call kasan_init_generic() which enables the static flag to mark KASAN
initialized in CONFIG_KASAN_GENERIC mode, otherwise it's an inline stub,
and the flag is enabled in kasan_init_sw_tags() or kasan_init_hw_tags().

Closes: https://bugzilla.kernel.org/show_bug.cgi?id=218315
