[PATCH v2 5/6] mm/page_owner: move free_ts_nsec output to free section in __dump_page_owner()

[Ye Liu]

The free_ts_nsec field is a free-event timestamp, but it was printed
in the allocation summary line alongside ts_nsec (allocation time).
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.
