[ Upstream commit e1c08cf23172ed6fb228d75efc9f4c80a6812116 ]
Call dwc2_debugfs_exit() and dwc2_hcd_remove() (if the HCD was enabled earlier) when usb_add_gadget_udc() has failed. This ensures that the debugfs entries created by dwc2_debugfs_init() as well as the HCD are cleaned up in the error path.
