If the removed check is in place, devices that need extra bus numbers
for their spawned VFs cannot spawn them (e.g. a dual port Intel 100G card),
and thus are limited in how many VFs that they support.
I removed this check and was able to spawn VFs that needed the extra
bus numbers, and nothing appeared to be wrong with the system
or the VF functionality, but I didn't do any extensive testing.
