Commit 2019ba0a01 ("block: Add AioContextNotifier functions to BB")
added blk_add/remove_aio_context_notifier() and implemented them by
passing through the bdrv_*() equivalent.
This doesn't work across bdrv_append(), which detaches child->bs and
re-attaches it to a new BlockDriverState. When
blk_remove_aio_context_notifier() is called we will access the new BDS
instead of the one where the notifier was added!
>From the point of view of the blk_*() API user, changes to the root BDS
should be transparent.
This patch maintains a list of AioContext notifiers in BlockBackend and
adds/removes them from the BlockDriverState as needed.
