vm_phys_enq_chunk() inserts a run of pages into the buddy queues. When
lazy initialization is enabled, only the first page of each run is
initialized; vm_phys_enq_chunk() thus initializes the page following the
just-inserted run.
This fails to account for the possibility that the page following the
run doesn't belong to the segment. Handle that in vm_phys_enq_chunk().
