block: Error out on load_vm with active dirty bitmaps

Loading a snapshot invalidates the bitmap. Just marking all blocks dirty
is not a useful response in practice, instead the user needs to be aware
that we switch to a completely different state. If they are okay with
losing the dirty bitmap, they can just explicitly delete it.

This effectively reverts commit 04dec3c3ae5.
