[PATCH] invalidate: remove_mapping() fix

If remove_mapping() failed to remove the page from its mapping, don't go and
mark it not uptodate!  Makes kernel go dead.

(Actually, I don't think the ClearPageUptodate is needed there at all).

Says Nick Piggin:

   "Right, it isn't needed because at this point the page is guaranteed
    by remove_mapping to have no references (except us) and cannot pick
    up any new ones because it is removed from pagecache.

    We can delete it."
