Mark Johnston e31fc3ab13 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().
