Currently we don't change the current value if device isn't in configured state. But in battery charging specification (section 1.2 and 1.4.13), it is mentioned that the device can draw up to 100mA of current if it's in unconfigured state. Hence add vbus draw work in composite_resume to draw 100mA if the device isn't configured.
