Mark Johnston 923da43e7c Fix a race in vm_page_dequeue_deferred_free() after r352110. 
This function loaded the page's queue index before setting PGA_DEQUEUE.
In this window the page daemon may have deactivated the page, updating
its queue index.  Make the operation atomic using vm_page_pqstate_cmpset();
the page daemon will not modify the page once it observes that PGA_DEQUEUE
is set.
