exit: fix misleading comment in forget_original_parent()

The commit 482a3767e508 ("exit: reparent: call forget_original_parent()
under tasklist_lock") moved the comment from exit_notify() to
forget_original_parent().  However, the forget_original_parent() only
handles (A), while (B) is handled in kill_orphaned_pgrp().  So remove the
unrelated part.
