Only expose streams mapped to audiopaths on configure() cb

When the configure() callback occurs for each audiopath, we only want
those streams that are mapped to the given audiopath to be exposed to
the audiopath. E.g. only streams mapped to loopback should be
propagated to loopback via configure() callback, rather than
all streams.
