Subject: [PATCH] vmscan: zone_reclaim don't call disable_swap_token()

Swap token don't works when zone reclaim is enabled since it was born.
Because __zone_reclaim() always call disable_swap_token() unconditionally.

This kill swap token feature completely.  As far as I know, nobody want to
that.  Remove it.
