Version 2:
- Added boot_initiator to hold the ibft initiator name
- Added boot_targetN to hold the corresponding ibft target name
- Moved the boot_nic net param extraction to the iscsi_sysfs_read_iface
- Added extra check before eluding to use the boot_nic info
For the case when iscsid is invoked for the first time after pivot root
during iSCSI boot, the boot connection would fail to re-connect if the
ibft/iscsi_boot sysfs entry contains tagged vlan.
The problem was caused by the lack of such info in the iscsi_session sysfs
for sync_session to inherit from.
The enclosed patchset does the following:
1. Extract and save the ibft->ethernetN name to the boot_context->boot_nic
2. Pass the boot_nic info to be saved to the sessionN sysfs
3. Extract the sessionN boot_nic sysfs info and retrieve the corresponding
   net params
This 'boot_nic' kernel session sysfs entry will only be present for ibft
boot.  Corresponding kernel drivers will have to add the ISCSI_PARAM_BOOT_NIC
attribute to its attr_is_visible table.

The last patch provides the fix for the unconditional overwrite of the
iface struct even after the ibft net info was already extracted.

Please review.  Thanks.
