To decrease it, the driver set skb->destructor to sock_edemux. However, it didn't work well, because the TCP stack also sets this destructor for early demux, and the refcount gets decreased only once, while increased two times (in mlx5e and in the TCP stack). It leads to a socket leak, a TLS context leak, which in the end leads to calling tls_dev_del twice: on socket close and on driver unload, which in turn leads to a crash. This commit fixes the refcount leak by calling sock_gen_put right away after using the socket, thus fixing all the subsequent issues.

It means there is always a minimal rate configured for every VF, even if user tries to remove it. In order to make QoS disable possible, check whether all vports have configured min_rate = 0. If this is true, set their bw_share to 0 to disable min_rate limitations.
