This patch fixes a race between when the disable cpu is marked online
and binding IPIs back to the CPU.  In some cases, an IPI would be sent
to CPU1 before it had allocated a new evtchn.  Moving smp_resume() call
before setting the cpu online fixes this race.  This fixes bug #228
(http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=228).
