mm/zswap: invalidate duplicate entry when !zswap_enabled
We have to invalidate any duplicate entry even when !zswap_enabled since
zswap can be disabled anytime. If the folio store success before, then
got dirtied again but zswap disabled, we won't invalidate the old
duplicate entry in the zswap_store(). So later lru writeback may
overwrite the new data in swapfile.
