AudioService: Fix SpatializerHelper asserts

Fix state update in onRoutingUpdated() in case of failure to
communicate to the native spatializer: this can cause an exception later
in setDispatchFeatureEnabledState(). Instead, try to recover by
triggering a reset.

Fix other places where exceptions are thrown instead of just logging an
error or triggering a reset.
