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]
