When forcing a sink role (eg. on transition from S3->S5), make sure we're not sourcing VBUS. Otherwise, if a power source is attached, we will fail to charge from it, due to the inability to sink and source VBUS simultaneously. BUG=chrome-os-partner:49544 chrome-os-partner:50343 TEST=Boot chell, attach USB-C peripheral, then power down chell. Remove USB-C peripheral, attach zinger, and verify PD negotiation + charging succeeds.
