Mark Johnston f93670b7b9 Stop clearing page flags in vm_page_pqbatch_submit().
All existing callers guarantee that the page does not have a
pre-existing dequeue pending.  Thus, if the page is dequeued before
pqbatch_submit() acquires the page queue lock, we do not need to do
anything since vm_page_dequeue_complete() takes care of clearing all
page queue state flags for us.

With this change, vm_page_pqbatch_submit() has the nice property that it
does not directly modify any fields in the page structure.
