[PATCH] crypto: cavium: fix memory leak on info

From: Colin Ian King <redacted>

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")
