The values previously returned by the Level Meter control were passed through from the interface without interpretation, but it has been discovered that the order of the values matches the mux assignment order (which is not presented to userspace). In addition, the values for disabled mux outputs, and mux outputs which share a source are invalid. This patch adds a per-device meter_map[], and a dynamic meter_level_map[] which is updated on routing changes. The meter level map gets used by scarlett2_meter_ctl_get() to both present the values in a standard order, and to fix up the invalid values by zeroing them (for disabled outputs) and copying them (for mux outputs which share a source).
