[SCSI] fcoe: config via separate create_vn2vn module parameter 



Add module parameter create_vn2vn that behaves like the create
parameter except that the new instance is created in FIP vn2vn mode.

This can be replaced once we change create to allow modifying
per-instance attributes before starting the instance.
