writeback: remove bdi_start_writeback()
bdi_start_writeback() is a thin wrapper on top of __wb_start_writeback() which is used only by laptop_mode_timer_fn(). This patches removes bdi_start_writeback(), renames __wb_start_writeback() to wb_start_writeback() and makes laptop_mode_timer_fn() use it instead. This doesn't cause any functional difference and will ease making laptop_mode_timer_fn() cgroup writeback aware.
