With commit 051f3ca02e46 ("sched/topology: Introduce NUMA identity node
sched domain") scheduler introduces an new numa level. However this
leads to numa topology on 2 node systems no more marked as NUMA_DIRECT.
After this commit, it gets reported as NUMA_BACKPLANE. This is because
sched_domains_numa_level is now 2 on 2 node systems.

Fix this by allowing setting systems that have upto 2 numa levels as
NUMA_DIRECT.

While here remove a code that assumes level can be 0.

Hey Peter,

Did you look at these two patches?

Nope, been on holidays and the inbox is an even bigger mess than normal.
I'll get to it, eventually :/
