[PATCH] exit: fix misleading comment in forget_original_parent()

[Fushuai Wang]

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.
