[PATCH 12/13] mm/memory-failure: remove obsolete comment in kill_proc()

[Miaohe Lin]

When user sets SIGBUS to SIG_IGN, it won't cause loop now. For action
required mce error, SIGBUS cannot be blocked. Also when a hwpoisoned
page is re-accessed, kill_accessing_process() will be called to kill
the process.
