input_log: preserve non-conditional routes when conditional routing is used

Remove early return in input_log_append() that prevented non-conditional
routes from receiving data when conditional routes existed. This ensures
both conditional and non-conditional routes receive data in mixed
configurations, preventing silent data loss from unconditional outputs.
