kasan: mark kasan_arg_stacktrace as __initdata

As kasan_arg_stacktrace is only used in __init functions, mark it as
__initdata instead of __ro_after_init to allow it be freed after boot.

The other enums for KASAN args are used in kasan_init_hw_tags_cpu(), which
is not marked as __init as a CPU can be hot-plugged after boot.  Clarify
this in a comment.
