kmsan_handle_dma_sg() has call to kmsan_handle_dma() function which was
missed during conversion to physical addresses. Update that caller too
and fix the following compilation error:

mm/kmsan/hooks.c:372:6: error: too many arguments to function call, expected 3, have 4
  371 |                 kmsan_handle_dma(sg_page(item), item->offset, item->length,
      |                 ~~~~~~~~~~~~~~~~
  372 |                                  dir);
      |                                  ^~~
mm/kmsan/hooks.c:362:19: note: 'kmsan_handle_dma' declared here
  362 | EXPORT_SYMBOL_GPL(kmsan_handle_dma);
