[dpdk-dev] [PATCH] crypto/dpaa2_sec: remove memset of icv on decryption side

[alok.makhariya at nxp.com]

From: Alok Makhariya <alok.makhariya at nxp.com>

Since the packet lengths are modified. It is not required to
explicitly reset the icv.

Fixes: 13273250eec5 ("crypto/dpaa2_sec: support AES-GCM and CTR")
Fixes: 8d1f3a5d751b ("crypto/dpaa2_sec: support crypto operation")
