usb: s3c-hsotg: do not disconnect gadget when receiving ErlySusp intr
DWC2 databook indicates if the core sets "ErlySusp" bit, an idle state has been detected on the USB for 3 ms. This situation can be occurred when waiting a request from user daemon. So, we should keep the connection between udc and gadget even though this interrupt is occurred.
