Zhengyuan Liu f7b76ac9d1 io_uring: fix counter inc/dec mismatch in async_list 
We could queue a work for each req in defer and link list without
increasing async_list->cnt, so we shouldn't decrease it while exiting
from workqueue as well if we didn't process the req in async list.

Thanks to Jens Axboe <axboe@kernel.dk> for his guidance.

Fixes: 31b5151064 ("io_uring: allow workqueue item to handle multiple buffered requests")
