mixin-mixout: fix frames-to-produce calculation 

When calculating the number of frames to produce, ignore inactive and
empty inputs. On the one hand an inactive empty input shouldn't block
producing data from active or non-empty inputs. OTOH if an inactive
input has pending data, it should be used instead of letting the data
stall.
