Subject: [PATCH] crypto: cavium - fix memory leak on info
Git-commit: 87aae50af730a28dc1d8846d86dca5e9aa724a9f
Patch-mainline: v4.16-rc1
References: bsc#1051510

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.

Detected by CoverityScan, CID#1408439 ("Resource Leak")
