Remove check for empty activePods list in CPUManager removeStaleState

Browse Source 
This check is redundant since we protect this call with a call to
`m.sourcesReady.AllReady()` earlier on. Moreover, having this check in
place means that we will leave some stale state around in cases where
there are actually no active pods in the system and this loop hasn't
cleaned them up yet. This can happen, for example, if a pod exits while
the kubelet is down for some reason. We see this exact case being
triggered in our e2e tests, where a test has been failing since October
when this change was first introduced.
