This caused issues when using op->sym->auth.digest.data for comparisons in AESNI_MB PMD after a subsequent patch enables SGL. For example, if segment size is 2, and digest size is 4, then 4 bytes are read from op->sym->auth.digest.data, which overflows into the memory after the segment, rather than using the second segment that contains the remaining half of the digest.
