Subject: crypto: cavium - fix memory leak on info

From: Colin Ian King <[email protected]>

[ Upstream commit 87aae50af730a28dc1d8846d86dca5e9aa724a9f ]

The object info is being leaked on an error return path, fix this by setting ret to -ENOMEM and exiting via the request_cleanup path that will free info.
