[SCSI] libiscsi,iser: patch for AHS support 



  - The default initialization of hdr_max is the minimum -
    sizeof(struct iscsi_cmd) - Once this patch goes into iser the default
    initialization at libiscsi can be removed.
  - This is not yet full support for AHSs at iser end. But it should be easy.
    Just allocate more space at iser_desc right after iscsi_hdr. Than
    at transmission time use ctask->hdr_len to retrieve the total
    size of all iscsi pdu headers. See previous patch at iscsi_tcp.[ch]
