solos-pci: fix double-free of TX skb in DMA mode

commit cae49ede00ec3d0cda290b03fee55b72b49efc11 upstream.

We weren't clearing card->tx_skb[port] when processing the TX done interrupt.
If there wasn't another skb ready to transmit immediately, this led to a
double-free because we'd free it *again* next time we did have a packet to
send.
