Alan Cox 96f1a84272 Replace the remaining uses of vm_radix_node_page() by vm_radix_isleaf() and
vm_radix_topage().  This transformation eliminates some unnecessary
conditional branches from the inner loops of vm_radix_insert(),
vm_radix_lookup{,_ge,_le}(), and vm_radix_remove().

Simplify the control flow of vm_radix_lookup_{ge,le}().
