Now it looks like we'll have multiple users of the iscsi transport
class, the iscsi initiator shouldn't really be a dependency of it. This
patch moves iscsi to being an initiator in its own right which selects
the transport attributes.
I think the reason it was a dependency was becuase the transport class
manages does the lifetime management/refcounting for the
initiators/iscsi_tcp.c session struct. scsi_transport_iscsi allocates
the scsi_host, and the initiator/iscsi_tcp.c's session structure is
allocated in that host_data.
