[SCSI] iscsi class, qla4xxx, iscsi_tcp, ib_iser: export/set initiator name

Browse Source 
For iscsi root boot, software iscsi needs to know what the BIOS/OF
initiator used for the initiator name so this puts it in sysfs
for userspace to be able to pick up.

For hw iscsi, it is nice to see what the card is using.

This patch adds the new param, and hooks in qla4xxx, iscsi_tcp, and ib_iser.
