usb: gadget: core: fix ->udc_set_speed() logic
Consider the following case: udc controller supports SuperSpeed. If we
first load a HighSpeed gadget followed by a SuperSpeed gadget, the
SuperSpeed gadget will be limited to HighSpeed as UDC core driver
doesn't call ->udc_set_speed() in the second case.
Call ->udc_set_speed() unconditionally to fix this issue.
This will also fix the case for dwc3 controller driver when SuperSpeed
gadget is loaded first and works in HighSpeed only as udc_set_speed()
was never being called.
