Subject: crypto: chelsio - Fix an error code in chcr_hash_dma_map()

From: Dan Carpenter <redacted>


[ 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.
