[PATCH 1/2] kasan: remove __kasan_save_free_info wrapper

[Sabyrzhan Tasbolatov <snovitoll@gmail.com>]

We don't need a kasan_enabled() check in
kasan_save_free_info() at all. Both the higher level paths
(kasan_slab_free and kasan_mempool_poison_object) already contain this
check. Therefore, remove the __wrapper.
