[dpdk-stable] [PATCH] drivers/crypto: fix wrongly assignment of digest_len

[Marko Kovacevic]

Fixes wrongly assignment of digest_len,
To assign session's auth digiest length by auth xform,
instead of cipher form. This caused a wrong truncated
mac size of AES-CMAC.

Fixes: 6491dbbecebb ("crypto/aesni_mb: support AES CMAC")
