Wu Fengguang 0d99519efe writeback: remove unused nonblocking and congestion checks ...

- no one is calling wb_writeback and write_cache_pages with
  wbc.nonblocking=1 any more
- lumpy pageout will want to do nonblocking writeback without the
  congestion wait

So remove the congestion checks as suggested by Chris.
