usb: dwc2: Fix memory leak in dwc2_hcd_init

commit 3755278f078460b021cd0384562977bf2039a57a upstream.

usb_create_hcd will alloc memory for hcd, and we should
call usb_put_hcd to free it when platform_get_resource()
fails to prevent memory leak.
goto error2 label instead error1 to fix this.

Fixes: 856e6e8e0f93 ("usb: dwc2: check return value after calling platform_get_resource()")
