Subject: ISCSISTART: Bring up the corresponding network interface for iboot

This is needed for the iSCSI offload boot.

Snip from M. Christie:
Note that we must bring up the interface before iface_setup_from_boot_context,
because we will want iscsi_sysfs_get_host_no_from_hwaddress to be able to match
a MAC to a iscsi host.  For some bnx2i cards, the card has to be ifupd for the
iscsi interface to have a MAC. If it is not ifupd we have seen MACs with all
zeros or no iscsi_hosts on different cards.
