mm/vmalloc.c: support HIGHMEM pages in vmap_pages_range_noflush()
If the pages being mapped are in HIGHMEM, page_address() returns NULL.
This probably wasn't noticed before because there aren't currently any
architectures with HAVE_ARCH_HUGE_VMALLOC and HIGHMEM, but it's simpler to
call page_to_phys() and futureproofs us against such configurations
existing.
