[PATCH 2/3] net: Avoid unnecessary calls to grub_net_tcp_retransmit

[Glenn Washburn]

In grub_net_poll_cards_idle_real, only call grub_net_tcp_retransmit if there
are network cards found. If there are no network card found, there can be no
tcp sockets to transmit on. So no need to go through that logic.
