Subject: [PATCH] isdn:hisax: Replace dev_kfree_skb_any by dev_consume_skb_any

The skb should be freed by dev_consume_skb_any() in hfcpci_fill_fifo()
when bcs->tx_skb is still used. The bcs->tx_skb is be replaced by
skb_dequeue(&bcs->squeue), so the original bcs->tx_skb should
be consumed(not drop).
