Miaohe Lin 8a78882dac mm/memory-failure: remove obsolete MF_MSG_DIFFERENT_COMPOUND ...

The page cannot become compound pages again just after a folio is split as
an extra refcnt is held.  So the MF_MSG_DIFFERENT_COMPOUND case is
obsolete and can be removed to get rid of this false assumption and code
burden.  But add one WARN_ON() here to keep the situation clear.
