[ Upstream commit 2360f9b8c4e81d242d4cbf99d630a2fffa681fab ]
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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
