usb: dwc3: Abort suspend on soft disconnect failure
commit 630a1dec3b0eba2a695b9063f1c205d585cbfec9 upstream.
When dwc3_gadget_soft_disconnect() fails, dwc3_suspend_common() keeps
going with the suspend, resulting in a period where the power domain is
off, but the gadget driver remains connected. Within this time frame,
invoking vbus_event_work() will cause an error as it attempts to access
DWC3 registers for endpoint disabling after the power domain has been
completely shut down.
Abort the suspend sequence when dwc3_gadget_suspend() cannot halt the
controller and proceeds with a soft connect.
