x86: Calgary: fix disable busnum for CalIOC2

The old check we used based on dev->bus->number is wrong for devices on
CalIOC2.  Instead look whether we have an IOMMU table for that bus - if
not, translation is disabled.

Thanks to Murillo Fernandes Bernardes <bernarde@br.ibm.com> for
spotting, suggesting a fix and testing.
