rS301223: Truncate HMAC output only if requested by the client
Summary

The output of HMAC was previously truncated to 12 bytes. This was only
correct in case of one particular crypto client - the new version of IPSEC.
Fix by taking into account the cri_mlen field in cryptoini session request
filled in by the client.
