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.
