Use load acquire semantics when reading the SQPOLL wakeup flag
...
Ensures that the wakeup flag is read after the tail pointer has been
written. It's important to use memory load acquire semantics for the
flags read, otherwise the application and the kernel might not agree on
the consistency of the wakeup flag, leading to I/O starvation.

Fix io_uring_sqe to use the names of the first member of each union
...
Now we're really future-proof... no more `opflags` creeping in.
When anonymous unions land, we can start using `accept_flags` etc.
Until then, code using this struct won't break when the kernel adds features.
