[PATCH] uvc: use usb_make_path to fill in usb_info

[Hans Verkuil]

The uvc driver uses this function to fill in bus_info for VIDIOC_QUERYCAP,
so use the same function when filling in the bus_info for the media device.

The current implementation only fills in part of the info. E.g. if the full
bus_info is usb-0000:01:00.0-1.4.2, then the media bus_info only has 1.4.2.
