cf9496376f block: vhdx: impl AsyncDiskFile for VhdxDiskSync
try_clone() shares the Arc<Mutex<Vhdx>>. new_async_io() creates
VhdxSync with a cloned Arc (no error path, infallible).

c06f6c3293 tests: fix CI flakiness
This test has failed at least once in upstream CI. With the applied

In other words: we will always be able to cancel.
