mm/cma: simplify zone intersection check

cma_activate_area walks all pages in the area, checking their zone
individually to see if the area resides in more than one zone.

Make this a little more efficient by using the recently introduced
pfn_range_intersects_zones() function.  Store the NUMA node id (if any) in
the cma structure to facilitate this.
