iommu/ipmmu-vmsa: Register in a sensible order

Browse source

IPMMU registers almost-initialised instances, but misses assigning the
drvdata to make them fully functional, so initial calls back into
ipmmu_probe_device() are likely to fail unnecessarily. Reorder this to
work as it should, also pruning the long-out-of-date comment and adding
the missing sysfs cleanup on error for good measure.
