Update the free page count when blacklisting pages.

Otherwise the free page count will not accurately reflect the physical
page allocator's state.  On 11 this can trigger panics in
vm_page_alloc() since the allocator state and free page count are
updated atomically and we expect them to stay in sync.  On 12 the
bug would manifest as threads looping in vm_page_alloc().
