Yeah, looks useful, not sure we want to change it last minute though.

I haven't checked if this is really necessary, but this missing teardown
was mentioned multiple times in previous reviews, so I just did it.
We can remove it once we have proven that it's pointless later.

TBH, this whole kvm_io_bus framework is really weird (I think
registering a new region copies every thing it had before) and designed
for the x86 use case. But it shouldn't be this series which fixes this.
