x86/apic, ACPI: Fix incorrect assignment when handling 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.
