Amir Goldstein be9857a4d2 ovl: fix memory leak in ovl_parse_param() ... commit 37f32f52643869131ec01bb69bdf9f404f6109fb upstream. On failure to parse parameters in ovl_parse_param_lowerdir(), it is necessary to update ctx->nr with the correct nr before using ovl_reset_lowerdirs() to release l->name.
