usb: usbtest: bmAttributes would better be masked
When transfer type is isochronous, the other bits (bits 5..2) of bmAttributes in endpoint descriptor might not be set zero. So it's better to use usb_endpoint_type routine to mask bmAttributes with USB_ENDPOINT_XFERTYPE_MASK to judge the transfter type later.
