Since commit14072ee33d("ubi: fastmap: Check wl_pool for free peb before wear leveling"), wear_leveling_worker() won't schedule fm_work if wear-leveling pool is empty, which could temporarily disable the wear-leveling until the fastmap is updated(eg. pool becomes empty). Fix it by scheduling fm_work if wl_pool is empty during wear-leveing.
