ide: Convert trim_aiocb_info.cancel to .cancel_async
We know that either bh is scheduled or ide_issue_trim_cb will be called
again, so we just set i, j and ret to the right values. In both cases,
ide_trim_bh_cb will be called.
Also forward the cancellation to the iocb->aiocb which we get from
bdrv_aio_discard.
