Only marker is guaranteed to be present on the queue after the relock
in vm_pageout_fallback_object_lock() and vm_pageout_page_lock(). The check for the m->queue == queue assumes that the page does belong to a queue. Modify the 'unchanged' calculation bu dereferencing the marker tailq pointers, which is known to belong to the queue. Since for a page m linked to the queue, m->queue must be equal to the queue index, assert this instead of checking.
