[PATCH] crypto/ipsec_mb: fix zuc256 maximum tag length

[Ciara Power]

The AESNI_MB PMD supports 8 and 16 byte tag lengths for ZUC256 when
intel-ipsec-mb version is 1.3 or newer.
The conditional check to enable these tag lengths had the incorrect
operator, which enabled 8 and 16 byte tag lengths for versions below 1.2,
which is not supported.

Fixes: 7babda4316f9 ("crypto/ipsec_mb: support all tag sizes for ZUC-EIA3-256")
