FineGrainedSlotManager checks whether resources need to reconcile but doesn't act on the result

There are a few locations in FineGrainedSlotManager where we check whether resources can/need to be reconciled but don't care about the result and just trigger the resource update (e.g. in FineGrainedSlotManager:626 and FineGrainedSlotManager:682). Looks like we could reduce the calls to the backend here.

It's not having a major impact because this feature is only used in the ActiveResourceManager which triggers checkResourceDeclarations and reevaluates the resourceDeclarations. Not sure whether I missed something here and there's actually a bigger issue with it. But considering that nobody complained about it in the past, I'd assume that it's not a severe issue.
