mm/vmscan: fix highidx argument type

for_each_zone_zonelist_nodemask wants an enum zone_type argument, but is
passed gfp_t:

  mm/vmscan.c:2658:9:    expected int enum zone_type [signed] highest_zoneidx
  mm/vmscan.c:2658:9:    got restricted gfp_t [usertype] gfp_mask
  mm/vmscan.c:2658:9: warning: incorrect type in argument 2 (different base types)
  mm/vmscan.c:2658:9:    expected int enum zone_type [signed] highest_zoneidx
  mm/vmscan.c:2658:9:    got restricted gfp_t [usertype] gfp_mask

convert argument to the correct type.
