[SCSI] iscsi class: Add session initiatorname and ifacename sysfs attrs.
This adds two new attrs used for creating initiator ports and binding sessions to hardware. The session level initiatorname: Since bnx2i does a scsi_host per host device, we need to add the iface initiator port settings on the session, so we can create multiple initiator ports (each with different inames) per device/scsi_host. The current iname reflects that qla4xxx can have one iname per hba, and we are allocating a host per session for software. The iname on the host will remain so we can export and set the hba level qla4xxx setting. The ifacename attr: To bind a session to a some peice of hardware in userspace we maintain some mappings, but during boot or iscsid restart (iscsid contains the user space part of the driver) we need to be able to figure out which of those host mappings abstractions maps to certain sessions. This patch adds a ifacename attr, which userspace can set to id the host side of the endpoint across pivot_roots and iscsid restarts.
