Subject: exit: add lock context annotation on find_new_reaper()
From: Namhyung Kim <namhyung@gmail.com>

find_new_reaper() releases and regrabs tasklist_lock but was missing
proper annotations.  Add it.  This remove following sparse warning:

 warning: context imbalance in 'find_new_reaper' - unexpected unlock
