Silence harmless sonos data structure warnings #12767
The recent Sonos rework increased the allowed logging because it appeared that SoCo did not produce logs at that level in normal operation.
However, a frequent but harmless warning has now been reported. This PR turns the logging level back down for the module emitting that warning.
I have not yet managed to produce the warning myself so the change is untested for the time being.
