net/mlx5: SF, Fix add port error handling

If failed to add SF, error handling doesn't delete the SF from the
SF table. But the hw resources are deleted. So when unload driver,
hw resources will be deleted again. Firmware will report syndrome
0x68def3 which means "SF is not allocated can not deallocate".

Fix it by delete SF from SF table if failed to add SF.
