Ioana Ciornei d5f4e19a85 dpaa2-eth: use the correct software annotation field
The incorrect software annotation field was being used, swa->sg.sgt_size
instead of swa->tso.sgt_size, which meant that the SGT buffer was
unmapped with a wrong size.
This is also confirmed by the DMA API debug prints which showed the
following:

[   38.962434] DMA-API: fsl_dpaa2_eth dpni.2: device driver frees DMA memory with different size [device address=0x0000fffffafba740] [map size=224 bytes] [unmap size=0 bytes]
[   38.980496] WARNING: CPU: 11 PID: 1131 at kernel/dma/debug.c:973 check_unmap+0x58c/0x9b0

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.
