How about, instead:

	- scan once looking for cs_nbfree > 0; return best found if any
	- scan once looking for cs_nffree > 0; return best found if any
	- return 0; mkdir will fail because the disk is full.

This has the advantage that the second pass will not pick a completely
full cylinder group..
