mm/writeback: commit reason of WB_REASON_FORKER_THREAD mismatch name
After commit 839a8e8660b6 ("writeback: replace custom worker pool implementation with unbound workqueue"), there is no bdi forker thread any more. However, WB_REASON_FORKER_THREAD is still used due to it is TPs userland visible and we won't be exposing exactly the same information with just a different name.
