This is part of resolving the deadlock mentioned in commit "block: move draining out of bdrv_change_aio_context() and mark GRAPH_RDLOCK". bdrv_root_unref_child() is called by: 1. blk_remove_bs(), where a drained section is introduced. 2. bdrv_unref_child(), which runs under the graph lock, so the drain will be moved further up to its callers. 3. block_job_remove_all_bdrv(), where a drained section is introduced. For all callers of bdrv_unref_child() and its generated bdrv_co_unref_child() coroutine variant, a drained section is introduced, they are not explicilty listed here. The caller quorum_del_child() holds the graph lock, so it is not actually allowed to drain. This will be addressed in the next commit.
