pulsesink: Enhance code readability in pulsesink_query
pulsesink: Enhance code readability in pulsesink_query

In pulsesink_query function, we use a switch for the query
type. In the CAPS case, there is no 'break', instead we
return right away. Use a break and return at the end of
the function instead for better code readability.
