xen/trace: Don't dump offline CPUs in debugtrace_dump_worker()

The 'T' debugkey reliably wedges on one of my systems, which has a sparse
APIC_ID layout due to a non power-of-2 number of cores per socket.  The
per_cpu(dt_cpu_data, cpu) calcution falls over the deliberately non-canonical
poison value.
