Remove code duplication in mm32.c by calling the native dma_ops if the page is a local page (not a foreign page). Use a simple pfn_valid(pfn) check to figure out if the page is local, exploiting the fact that dom0 is mapped 1:1, therefore pfn_valid always returns false when called on a foreign mfn.
