Since commit 9facd54a45 "x86/ioapic: Add register level checks to detect
bogus io-apic entries", Xen is able to cope with IO APICs not mapped in
the fixmap.
Therefore the whole logic to allocate a fake page for some IO APICs is
unnecessary.
With the logic removed, the code can be simplified a lot as we don't
need to go through all the IO APIC if SMP has not been detected or a
bogus zero IO-APIC address has been detected.
To avoid another level of tabulation, the simplification is now moved in
its own function.

Thank you! I took the liberty to push them.
