e2e: topomgr: remove single-numa node hack

On single-NUMA node systems the numa_node of sriov devices was
sometimes reported as "-1" instead of, say, 0. This makes some
tests that should succeed[0] fail unexpectedly.

The reporting works as expected on real multi-NUMA node systems.

This small workaround was added to handle this corner case,
but it makes overall the code less readable and a bit too lenient,
hence we remove it.

[0] on a single NUMA node system some resources are obviously
always aligned if the pod can be admitted. It boils down to the
node capacity at pod admittal time.
