[PATCH for-8.1] Misc Xen-on-KVM fixes

[David Woodhouse]

A few minor fixes for the Xen emulation support. One was just merged, but
there are three outstanding.

David Woodhouse (3):
      hw/xen: fix off-by-one in xen_evtchn_set_gsi()
      i386/xen: consistent locking around Xen singleshot timers
      hw/xen: prevent guest from binding loopback event channel to itself
