crypto: cavium - fix memory leak on info

Browse source 
[ Upstream commit 87aae50af7 ]

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")
