[SCSI] bfa: add fc transport class based vport create/delete
Use duplicate fc transport template for physical and vitual port. Add vport create/delete/disalbe functions in the transport template of physical port. Changes to make the vport create/delete function to work under this framework. Signed-off-by: Jing Huang <huangj@brocade.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
