This supersedes the "virtio: Register host notifier handler as external" patch from yesterday.
The bug was initially reported by Matthew Schumacher as LaunchPad Bug 1570134, and nicely bisected by Max Reitz. See patch 2 for the analysis. We are late for 2.6 so the fix is done locally in mirror.c. In 2.7 we should revisit this and let bdrv_drained_begin do the work.
