[LTP] [PATCH v2 2/2] tcindex01: Pass if the tcindex module is blacklisted

[Martin Doucha]

The tcindex01 test currently fails if the tcindex module is enabled
in kernel config but cannot be autoloaded. Some distros chose
to blacklist the module rather than remove it completely, thus
check for autoload failure and pass in that case.

- Use NETDEV_ADD_TRAFFIC_FILTER_RET() macro instead of the underlying function
