vfio-pci: Unmap and retry DMA mapping
Occasionally we get regions added that overlap with existing mappings.
These always seems to be in the VGA ROM range. VFIO returns EBUSY
for these mapping attempts. We can try a little harder and assume
that the latest mapping is correct by removing any overlapping ranges
and retrying the original request.
