Subject: [PATCH] usb: gadget: epautoconf: Use USB API functions rather than constants

Use the function usb_endpoint_type() rather than constants.

The Coccinelle semantic patch is as follows:

@@ struct usb_endpoint_descriptor *epd; @@

- (epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\))
+ usb_endpoint_type(epd)
