From: Zlatko Calusic <zlatko.calusic@iskon.hr>
Commit 92df3a723f ("mm: vmscan: throttle reclaim if encountering too
many dirty pages under writeback") introduced waiting on congested zones
based on a sane algorithm in shrink_inactive_list().
What this means is that there's no more need for throttling and
additional heuristics in balance_pgdat(). So, let's remove it and tidy
up the code.
