mtd, 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(). 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. Detected this behaviour on the dxr2 board, where the UBI fastmap gets not written when attaching/dettaching on an empty NAND. It drops instead the error message: could not find any anchor PEB With this patch, fastmap gets written on dettach.
