[SCSI] libfcoe: Allow FIP to be disabled by the driver
Allow FIP to be disabled by the driver for devices that want to use libfcoe in non-FIP mode. The driver merely sets the fcoe_ctlr mode to the state which should be entered when the link comes up. The default is auto. No change is needed for fcoe.c which uses auto mode.
