mm: Revert accounting for WRITEBACK_TEMP in balance_dirty_pages
We don't have to account WRITEBACK_TEMP in balance_dirty_pages anymore
because
of "strictlimit" feature: fuse marks its bdi with BDI_CAP_STRICTLIMIT, so
balance_dirty_pages knows that for fuse it should always pay attention to
per-bdi limits and counters.
Kudos to Andrey Ryabinin for pointing out.
