Subject: [PATCH v2 5/6] fs/writeback: correct comment of __wakeup_flusher_threads_bdi

Commit e8e8a0c6c9bfc ("writeback: move nr_pages == 0 logic to one
location") removed parameter nr_pages of __wakeup_flusher_threads_bdi
and we try to writeback all dirty pages in __wakeup_flusher_threads_bdi
now. Just correct stale comment.
