David Woodhouse af0ce40996 intel-iommu: Cope with broken HP DC7900 BIOS ...

commit 0815565adfe3f4c369110c57d8ffe83caefeed68 upstream.

Yet another reason why trusting this stuff to the BIOS was a bad idea.
The HP DC7900 BIOS reports an iommu at an address which just returns all
ones, when VT-d is disabled in the BIOS.

Fix up the missing iounmap in the error paths while we're at it.
