Fix a stupid bug with recent poll locking optimisations and also add two
clean ups on top.

Pavel Begunkov (4):
  io_uring: don't miss setting REQ_F_DOUBLE_POLL
  io_uring: don't race double poll setting REQ_F_ASYNC_DATA
  io_uring: clear REQ_F_HASH_LOCKED on hash removal
  io_uring: consolidate hash_locked io-wq handling
