When the old value and new one are the same the emulator skips the
write; this is undesiderable when the destination is a MMIO area and the
write shall be performed regardless of the previous value. This
optimization breaks e.g. a Linux guest APIC compiled without
X86_GOOD_APIC.

Remove the check and always perform the writeback stage in the
emulation.


Applied this and the next patch. Thanks!
