media: go7007: Fix URB type for interrupt handling
Josef reported that his old-and-good Plextor ConvertX M402U video converter spews lots of WARNINGs on the recent kernels, and it turned out that the device uses a bulk endpoint for interrupt handling just like 2250 board. For fixing it, generalize the check with the proper verification of the endpoint instead of hard-coded board type check.
