In UEK7 and later kernels CSD framework is being used for task wakeup. So now in a CPU's call_single_queue we will have CSDs for task wakeup as well and these will not have source and destination fields initialized.

Report task wakeup CSDs separately and avoid these CSDs being treated as ones with both source and destination as cpu 0.
