    Sync with amd64/arm/arm64/i386/mips pmap change r288256:
  
    Exploit r288122 to address a cosmetic issue.  Since PV chunk pages don't
    belong to a vm object, they can't be paged out.  Since they can't be paged
    out, they are never enqueued in a paging queue.  Nonetheless, passing
    PQ_INACTIVE to vm_page_unwire() creates the appearance that these pages
    are being enqueued in the inactive queue.  As of r288122, we can avoid
    this false impression by passing PQ_NONE.
