SepAccessCheckEx is broken

    Description

      SepAccessCheckEx doesn't properly validate the access rights. It has a hack to allow access, even though it could not get all rights.
      DPRINT("HACK: RemainingAccess = 0x%08lx DesiredAccess = 0x%08lx\n", RemainingAccess, DesiredAccess);
      I demoted it to a DPRINT, since it's massively spamming the log. This needs to be fixed!
