UPSTREAM: usb: dwc3: gadget: Change condition for processing suspend event

Currently we process the suspend interrupt event only if the
device is in configured state. Consider a case where device
is not configured and got suspend interrupt, in that case our
gadget will still use 100mA as composite_suspend didn't happen.
But battery charging specification (BC1.2) expects a downstream
device to draw less than 2.5mA when unconnected OR suspended.

Fix this by removing the condition for processing suspend event,
and thus composite_resume would set vbus draw to 2.
