Relax an assertion in vm_pqbatch_process_page().

While executing vm_pqbatch_process_page(m), m->queue may change to
PQ_NONE if the page daemon is concurrently freeing the page.  In this
case m's queue state flags must be clear, so vm_pqbatch_process_page()
will be a no-op, but the race could cause spurious assertion failures.
Correct the assertion which assumed that m->queue's value does not
change while the page queue lock is held.
