Finish randominzing remaining layers of pmap_kernel
An earlier diff moved the top level page, this diff finishes the lower
layers. New pages are allocated for the existing hiererchy (which thus
benefit from random placement from pmemrange/etc). Existing managed
pages are returned to uvm (a small number of bootstrap pages are not
returned as they are allocated in locore0 and thus aren't managed).
