Pavel Begunkov 569f5308e5 io_uring: fix false positive KASAN warnings 
io_req_local_work_add() peeks into the work list, which can be executed
in the meanwhile. It's completely fine without KASAN as we're in an RCU
read section and it's SLAB_TYPESAFE_BY_RCU. With KASAN though it may
trigger a false positive warning because internal io_uring caches are
sanitised.

Remove sanitisation from the io_uring request cache for now.
