block: Remove wrong bdrv_set_aio_context() calls
The mirror and commit block jobs use bdrv_set_aio_context() to move their filter node into the right AioContext before hooking it up in the graph. Similarly, bdrv_open_backing_file() explicitly moves the backing file node into the right AioContext first. This isn't necessary any more, they get automatically moved into the right context now when attaching them. However, in the case of bdrv_open_backing_file() with a node reference, it's actually not only unnecessary, but even wrong: The unchecked bdrv_set_aio_context() changes the AioContext of the child node even if other parents require it to retain the old context. So this is not only a simplification, but a bug fix, too. Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1684342 Signed-off-by: Kevin Wolf <kwolf@redhat.com>
