This improves the error messages on my ts433 from

	WARNING: mmc0: Failed to create link from mmc0.primary to mmc0
	WARNING: mmc0: Failed to create link from mmc0.primary to mmc0
	WARNING: mmc0: Failed to create link from mmc0.primary to mmc0
	WARNING: mmc0: Failed to create link from mmc0.primary to mmc0
	WARNING: mmc0: Failed to create link from mmc0.primary to mmc0

to 

	WARNING: mmc0: Failed to create link from mmc0.primary to mmc0.2
	WARNING: mmc0: Failed to create link from mmc0.primary to mmc0.3
	WARNING: mmc0: Failed to create link from mmc0.primary to mmc0.4
	WARNING: mmc0: Failed to create link from mmc0.primary to mmc0.5
	WARNING: mmc0: Failed to create link from mmc0.primary to mmc0.6

I still don't understand why barebox intends to create mmc0.primary for
all these partitions, but still it's an obviously right improvement.
