[dpdk-stable] [PATCH v1] test: fix ipsec unit test segfault

[Ruifeng Wang]

Segfault was observed when running ipsec unit test:

 + TestCase [10] : test_ipsec_replay_inb_repeat_null_null_wrapper
                   succeeded
 + TestCase [11] : test_ipsec_replay_inb_inside_burst_null_null_wrapper
                   succeeded
 + TestCase [12] : test_ipsec_crypto_inb_burst_2sa_null_null_wrapper
                   succeeded
 + TestCase [13] : test_ipsec_crypto_inb_burst_2sa_4grp_null_null_wrapper
                   succeeded
Segmentation fault

Data corruption happens due to incorrect destroy of session. Security
session needs process different from crypto session.

Destroy corresponding sessions according to different security actions.

Fixes: 05fe65eb66b2 ("test/ipsec: introduce functional test")
