Only really an optimization (plus it makes the code a little conceptually simpler).

Instead of manually specifying success or failure.
Based on test_return_status() in ntoskrnl. The changes in this patch don't
affect device IRPs, but the tests show the heuristic that Windows uses, and in
practice it turns out to be correct for all known asyncs.

Mostly just to simplify the interface, so that we don't need to use the return
value to communicate this.

In particular, don't mark asyncs with output data as "alerted", i.e.
restartable.

For convenience, and to centralize the STATUS_ALERTED logic into one place.

We still don't quite handle this completely correctly, but we should at least
avoid crashing the server due to a failed assertion.

At best this is a no-op. At worst this will emit an extra APC_ASYNC_IO where
the termination (e.g. cancellation) should already have emitted one.

This semantically reverts 481517178f.
That commit was used to implement NtFlushBuffersFile, which at the time didn't
use a callback function. 9050b58f07 changed it to
use irp_completion(), since the result of a blocking flush needed to be taken
from the IOSB.
As of 97afac469f that's not true anymore, but on
the other hand it is theoretically possible for a device driver to touch the
Information member of the IOSB, and we don't seem to lose anything by making
all asyncs take a common path.
Since all asyncs pass user data and there's no clear reason for them not to,
let's get rid of a bit of extra code complexity that's no longer used.

Steam uses WSASend() with completion ports, reusing OVERLAPPED structures as
soon as they are returned from GetQueuedCompletionStatus(). Since completion is
queued during the select request in wait_async(), the I/O status block can be
reused even before the call to NtDeviceIoControl exits.
This works fine with current Wine, because WSASend() doesn't access the I/O
status block after queuing completion. However, a patch that changes it to use
wait_async() like other async requests causes NtDeviceIoControlFile to
consistently return garbage status codes.
