[Patch v2] x86, ACPI: Fix the wrong assignment when Handle apic/x2apic entries

By pure accident the bug makes no functional difference, because the only
expression where we are using these values is (!count && !x2count), in which
the variables are interchangeable, but it makes sense to fix the bug
nevertheless.
