io_uring: Add KASAN support for alloc_caches
Add support for KASAN in the alloc_caches (apoll and netmsg_cache).
Thus, if something touches the unused caches, it will raise a KASAN
warning/exception.
It poisons the object when the object is put to the cache, and unpoisons
it when the object is gotten or freed.
