EffectBundle: check nb channels to write speaker angles
When speaker angles are queried, the size of the array for the
returned data is 3x the number of channels (where really it
should be max(2, nbChannels)). The code assumed it was at
least 3x2 (where 2 is the number of virtual speakers this
effect supports) and would thus crash when called for a mono
channel mask.
