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.
