[dpdk-dev] [PATCH 03/13] librte_security: fix session counter

[Lukasz Wojciechowski]

Fix session counter to be decreased in rte_security_session_destroy
only when session was successfully destoyed.

Formerly session counter was decreased prior session destroying
and returning session object to mempool. It remained decreased even
if session was not destroyed and mempool object released making counter
invalid.
