[v3 1/2] crypto/qat: fix CCM request descriptor hash_state_sz field

[Emma Finn]

The hash_state_sz field in the QAT request descriptor for AES-CCM
operations was incorrectly set to the digest length. According to
the QAT firmware specification, this field should contain the
length of AAD in quadwords for CCM operations.

Fixes: ab56c4d9ed9a ("crypto/qat: support AES-CCM")
