scsi: libfc: Replace ->seq_start_next callback with function call
The ->seq_start_next callback only ever had one implementation, so call the function directly and drop the callback. Signed-off-by: Hannes Reinecke <hare@suse.com> Acked-by: Johannes Thumshirn <jth@kernel.org> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
