MLK-11151 usb: chipidea: otg: drive vbus off if fsm.drv_vbus is true
The current condition may not true even we have driven vbus on already.
The vbus drive operation may be async, eg through i2c gpio expendor,
so the vbus may not be valid when we unload usb module.
We meet this issue when we do fast load/unload usb module test.
