Move it to the free section where it logically belongs, together with free_pid and free_tgid. This also makes __dump_page_owner() consistent with print_page_owner(), which only prints ts_nsec in the allocation summary. The output now groups all free-related information (pid, tgid, timestamp, stack trace) in one place. No functional change except output formatting.
