ASoC: SDCA: Add missing default in switch in entity_pde_event()

Browse Source 
The current code should be safe as the PDE widget only registers for the
two events handled in the switch statement. However, it is causing a
smatch warning and also is a little fragile to future code changes, add
a default case to avoid the warning and make the code more robust.
