splice: return type ssize_t from all helpers
...
Not sure why some splice helpers return long, maybe historic reasons.
Change them all to return ssize_t to conform to the splice methods and
to the rest of the helpers.

io_uring/splice: use fput() directly
...
No point in using io_file_put() here, as we need to check if it's a
fixed file in the caller anyway.

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.

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.

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.
