crypto: ixp4xx - dma_unmap the correct address
[ Upstream commit 9395c58fdddd79cdd3882132cdd04e8ac7ad525f ]
Testing ixp4xx_crypto with CONFIG_DMA_API_DEBUG lead to the following error:
DMA-API: platform ixp4xx_crypto.0: device driver tries to free DMA memory it has not allocated [device address=0x0000000000000000] [size=24 bytes]
This is due to dma_unmap using the wrong address.
Fixes: 0d44dc59b2b4 ("crypto: ixp4xx - Fix handling of chained sg buffers")
