crypto: gcm - fix assumption that assoc has one segment
rfc4543(gcm(*)) code for GMAC assumes that assoc scatterlist always contains only one segment and only makes use of this first segment. However ipsec passes assoc with three segments when using 'extended sequence number' thus in this case rfc4543(gcm(*)) fails to function correctly. Patch fixes this issue.
