ASoC: Stop checking for supplied widgets after we find the first
We don't really care how many widgets a supply is supplying, we just care if the number is non-zero. This didn't actually produce any improvement in the test cases I've been using but seems obviously sensible enough that I'm pushing it out anyway. We could do a similar thing for other widgets but this may be unhelpful for further refactorings Liam was working on aiming to allow us to identify connected audio paths.
