Reorder USB_STATE updates so config_changed is not replaced.

Because of flag INTENT.ACTION_REPLACE_PENDING, intents
sent in rapid succession could replace previous intents
that have not been processed, and it is unreliable when
or whether this happens. Since CONFIG_CHANGED cannot afford
to be lost, make sure it is sent last, so it is always
processed.
