crypto: cavium - fix memory leak on info
[ 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.
Detected by CoverityScan, CID#1408439 ("Resource Leak")
Fixes: c694b233295b ("crypto: cavium - Add the Virtual Function driver for CPT")
