Bug: crypto_snow3g failed in Auth snow3g + Cipher snow3g

[coolwilled]

Hi,
I run "pdcp_autotest"  with --vdev=crypto_snow3g in app/dpdk-test in dpdk
v25.11.
When i = 42 in run_test_for_one_know_vec() in test_pdcp.c,
It is PDCP control plane Auth snow3g gen + Cipher sonw3g enc,
the case failed because the last 4 bytes is cleared in
last for() loop in line 167 in  process_snow3g_cipher_op() in pmd_snow3g.c .

It can be fixed with following change:

diff --git a/drivers/crypto/ipsec_mb/pmd_snow3g.c
