Hi,

#1 disables multishot requests for double waitqueue users for now, it's
got a few corner cases that need hashing out.

#2 is a prep patch for #3, which ties the ->apoll lifetime with that of
the request instead of keeping it seperate. That's more logical and makes
it handled more like other dynamically allocated items.

Since v1:

- Turn double wait multishot into single-shot. The application logic
  won't change for that, it'll just be a bit less efficient as it'll
  require a re-arm for each trigger. It effectively just turns
  multishot into single shot mode for double wait use cases (which are
  rare).
- Add flag checking helper and make the io_clean_op() call conditional
  again.
