crypto/aesni_mb: add missing digest length

AESNI MB now supports authentication only operations,
but the array containing all the possible digest lengths
was not updated to reflect the new algorithm NULL_HASH,
causing an "Out-of-bounds access".

Coverity issue: 140977
Fixes: 8772c3f713e2 ("crypto/aesni_mb: add single operation functionality")
