Specifically, I think it avoids the blkreplay_open/close sequence. Is
this what is needed to make it work?
We should probably mention in the commit message the exact reason why
implementing .bdrv_snapshot_goto, but not the other snapshot related
callbacks, fixes things. If you confirm my assumption, I can add that
while applying.
