dspmanager: Catch ALL the exceptions!

 * There are very few times where catching Exception is appropriate, but
   in this case it's appropriate to do four times in a row. Due to
   various issues with device switching and other weirdness, an effect
   might fail to set. Let's just hide it instead of crashing the app.

Actually add digital dock intent to the filter.

 * Also make updateDsp synchronized to avoid badness.
