crypto: chelsio - Fix an error code in chcr_hash_dma_map()
[ Upstream commit 7814f552ff826fefa5e1b24083c7a06a9378e9ef ]
The dma_map_sg() function returns zero on error and positive values on
success. We want to return -ENOMEM on failure here and zero on success.
Fixes: 2f47d5804311 ("crypto: chelsio - Move DMA un/mapping to chcr from lld cxgb4 driver")
