mach_vm_region_recurse calls have invalid parameter specified on Tiger

[GoogleCodeExporter]

mach_vm_region_recurse will return KERN_INVALID_ARG (4) if the info_count
parameter is VM_REGION_SUBMAP_INFO_COUNT.  However, this works on Leopard
due to coarse-grained error checking (see function vm_map_region_recurse_64
in osfmk/vm/vm_map.c; look at the lines that do parameter checking on *count)

Issue 255 tracks consolidating two duplicate functions, but for now I'm
making the fix in both functions because there's someone waiting on this fix.
