Mark Johnston aac25e2225 pmap: Fix largemap restart checks in the kernel_maps sysctl handler
The purpose of these checks is to ensure that the address of the
next-level page table page is valid, since nothing is synchronizing with
a concurrent update of the large map and large map PTPs are freed to the
system.  However, if PG_PS is set, there is no next level.
