Jens Axboe 4bcb982cce io_uring: expand main struct io_kiocb flags to 64-bits 
We're out of space here, and none of the flags are easily reclaimable.
Bump it to 64-bits and re-arrange the struct a bit to avoid gaps.

Add a specific bitwise type for the request flags, io_request_flags_t.
This will help catch violations of casting this value to a smaller type
on 32-bit archs, like unsigned int.

This creates a hole in the io_kiocb, so move nr_tw up and rsrc_node down
to retain needing only cacheline 0 and 1 for non-polled opcodes.

No functional changes intended in this patch.
