I'm not 100% sure this is the right thing to do. It seems the only
usecase of this function is to print slightly more useful error messages than
we would get should we only call devfs_add_partition("disk.1",...)
from boards directly.

Anyway, two boards are using it, the whole thing has a negative
diffstat, so I applied it.
