[HVM] Fix a bug in the emulation of the xchg instruction.

This bug has prevented us from booting fully virtualized SMP guests
that write to the APIC using the xchg instruction (when
CONFIG_X86_GOOD_APIC is not set). On 32 bit platforms, sles 10 kernels
are built without CONFIG_x86_GOOD_APIC not set and hence we have had
problems booting fully virtualized SMP sles 10 guests.
