[dpdk-dev] [PATCH 2/2] crypto/scheduler: fix memory leak

[Pablo de Lara <pablo.de.lara.guarch@intel.com>]

If private context creation fails, the memory
allocated for it and for some of the rings created
was being leaked.
In case of failure, it must be freed.

Fixes: 4c07e0552f0a ("crypto/scheduler: add multicore scheduling mode")
