--------------------------------

[ Upstream commit 2360f9b8 ]

In pch_gbe_xmit_frame(), NETDEV_TX_OK will be returned whether
pch_gbe_tx_queue() sends data successfully or not, so pch_gbe_tx_queue()
needs to free skb before returning. But pch_gbe_tx_queue() returns without
freeing skb in case of dma_map_single() fails. Add dev_kfree_skb_any()
to fix it.
