Switch to using map_guest_area(). Noteworthy differences from
map_vcpu_info():
- remote vCPU-s are paused rather than checked for being down (which in
principle can change right after the check),
- the domain lock is taken for a much smaller region,
- the error code for an attempt to re-register the area is now -EBUSY,
- we could in principle permit de-registration when no area was
previously registered (which would permit "probing", if necessary for
anything).
