Paolo Bonzini 5b8bb3595a async: add aio_bh_schedule_oneshot ... qemu_bh_delete is already clearing bh->scheduled at the same time as it's setting bh->deleted. Since it's not using any memory barriers, there is no synchronization going on for bh->deleted, and this makes the bh->deleted checks superfluous in aio_compute_timeout, aio_bh_poll and aio_ctx_check. Just remove them, and put the (bh->scheduled && bh->deleted) combo to work in a new function aio_bh_schedule_oneshot. The new function removes the need to save the QEMUBH pointer between the creation and the execution of the bottom half.
