Currently in udc_stop, if vbus_active flag is true, all USB activities
will be stopped, but vbus_active flag is still left to be true,
this causes issue, when afterwards driver tries to connect gadget
device to host, But due to the uncleared vbus_active, some necessary
setup steps are skipped.
This patch clears vbus_active flag in udc_stop callback.
