PATCH 1/1 ia64 IOSAPIC bogus error cleanup

Tony suggested a simplification to my original post on lkml, the result is this patch.

On Altix (sn2) machines the "Error parsing MADT" message is misleading because the lack of IOSAPIC entries is expected.

Since I am sure someone will ask, I have been told that the chance of this changing anytime soon is close to nil.
