xentrace: handle sparse cpu ids correctly in xen trace buffer handling

The per-cpu buffers for Xentrace are addressed by cpu-id, but the info
array for the buffers is sized only by number of online cpus. This
might lead to crashes when using Xentrace with smt=0.

The t_info structure has to be sized based on nr_cpu_ids.
