UBI: Set free_count to zero before walking through erase list
Set free_count to zero before walking through ai->erase list in wl_init(). Found in U-Boot as U-Boot has no workqueue/threads, it immediately calls erase_worker(), which increase for each erased block free_count. Without this patch, free_count gets after this initialized to zero in wl_init(), so the free_count variable always has the maybe wrong value 0 in U-Boot.
