scatterlist: use sg_phys()
Coccinelle cleanup to replace open coded sg to physical address
translations. This is in preparation for introducing scatterlists that
reference __pfn_t.
// sg_phys.cocci: convert usage page_to_phys(sg_page(sg)) to sg_phys(sg)
// usage: make coccicheck COCCI=sg_phys.cocci MODE=patch
