For non-batch backends execute_async submits the kernel I/O inline
before returning. An early return while processing before inserting in
inflight_requests, meant the request went untracked, the local batch
list was never appended to inflight_requests, even though the request is
pending in the kernel.
To track it, insert into self.inflight_requests as soon as execute_async
returns Ok. The completion path's find_inflight_request now matches the
orphan and the bounce buffer is freed only after the kernel signals it
is done.
