[PATCH] Cleanup misleading IA64 ACPI error message

[George Beshers <gbeshers@gmail.com>]

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.
