topology: avoid unnecessary warning prints

Browse Source 
Doing strings.Split with a non-empty separator against a potentially
empty string (hint.NUMAs) may return an empty string in a slice of
size one, which then doesn't parse nicely with ParseInt and results
in a repeating warning.

It is better to check for hint.NUMAs emptiness before trying to
split it.
