Paolo Bonzini fed105e275 virtio-blk-dataplane: delete bottom half before the AioContext is freed 
Other uses of aio_bh_new are safe as long as all scheduled bottom
halves are run before an iothread is destroyed, which bdrv_drain will
ensure:

- archipelago_finish_aiocb: BH deletes itself

- inject_error: BH deletes itself

- blkverify_aio_bh: BH deletes itself

- abort_aio_request: BH deletes itself

- curl_aio_readv: BH deletes itself

- gluster_finish_aiocb: BH deletes itself

- bdrv_aio_rw_vector: BH deletes itself

- bdrv_co_maybe_schedule_bh: BH deletes itself

- iscsi_schedule_bh, iscsi_co_generic_cb: BH deletes itself

- laio_attach_aio_context: deleted in laio_detach_aio_context,
called through bdrv_detach_aio_context before deleting the iothread

- nfs_co_generic_cb: BH deletes itself

- null_aio_common: BH deletes itself

- qed_aio_complete: BH deletes itself

- rbd_finish_aiocb: BH deletes itself

- dma_blk_cb: BH deletes itself

- virtio_blk_dma_restart_cb: BH deletes itself

- qemu_bh_new: main loop AioContext is never destroyed

- test-aio.c: bh_delete_cb deletes itself, otherwise deleted in
the same function that calls aio_bh_new
