Dylan Yudaken aebb224fd4 io_uring: for requests that require async, force it 
Some requests require being run async as they do not support
non-blocking. Instead of trying to issue these requests, getting -EAGAIN
and then queueing them for async issue, rather just force async upfront.

Add WARN_ON_ONCE to make sure surprising code paths do not come up,
however in those cases the bug would end up being a blocking
io_uring_enter(2) which should not be critical.

Stefan Metzmacher f2ccb5aed7 io_uring: make io_kiocb_to_cmd() typesafe 
We need to make sure (at build time) that struct io_cmd_data is not
casted to a structure that's larger.

Pavel Begunkov 27a9d66fec io_uring: kill extra io_uring_types.h includes 
io_uring/io_uring.h already includes io_uring_types.h, no need to
include it every time. Kill it in a bunch of places, it prepares us for
following patches.
