Subject: [PATCH] security: fix crash on destroy null session

[ upstream commit 8a29f519ef1b2fdddb0324e867006c76c70173cb ]

rte_security_session_destroy should return -EINVAL if session is NULL,
but segfaults because of rte_mempool_from_obj(NULL) call.

Fixes: c261d1431bd8 ("security: introduce security API and framework")
