[SCSI] libiscsi_tcp: support padding offload
cxgb3i does not offload the processing of the header, but it will always process the padding. This patch adds a padding offload flag to detect when the LLD supports this. The patch also modifies the header processing so that we do not try to read/bypass the header dugest in the skb. cxgb3i will not include it with the header like with other offload cards.
