For the userspace it is needed to distinguish between requests for the control or streaming interface. The userspace would have to parse the configfs to know which interface index it has to compare the ctrl requests against. Since the interface numbers are not fixed, e.g. for composite gadgets, the interface offset depends on the setup. The kernel has this information when handing over the ctrl request to the userspace. This patch removes the offset from the interface numbers and expose the default interface defines in the uapi g_uvc.h.
