[SCSI] iscsi class, iscsi_tcp/iser: add host arg to session creation
iscsi offload (bnx2i and qla4xx) allocate a scsi host per hba, so the session creation path needs a shost/host_no argument. Software iscsi/iser will follow the same behabior as before where it allcoates a host per session, but in the future iser will probably look more like bnx2i where the host's parent is the hardware (rnic for iser and for bnx2i it is the nic), because it does not use a socket layer like how iscsi_tcp does.
