Andrey Konovalov 8ab3b09755 io_uring: use mempool KASAN hook
Use the proper kasan_mempool_unpoison_object hook for unpoisoning cached
objects.

A future change might also update io_uring to check the return value of
kasan_mempool_poison_object to prevent double-free and invalid-free bugs. 
This proves to be non-trivial with the current way io_uring caches
objects, so this is left out-of-scope of this series.
