Revert quicklist need->flush fix

Did not fix the reported issue. Apart from other weirdness this causes a
bad link between the TLB flushing logic and the quicklists. If there is
indeed an issue that an arch needs a tlb flush before free then the arch
code needs to set tlb->need_flush before calling quicklist_free.
