Currently the code expects that the device found at
/sys/char/$maj:$min/device for USB devices is a "usb_device". However,
at least for some devices, such as for the udl driver, they are instead
a "usb_interface".
A usb_interface is a child of the usb_device we're interested in, so we
walk up one in the /sys path to get there.
For example, with a USB device I have, trimmed to show the relevant
information:
```

Mesa expects to be able to map the same buffer, without unmapping it.
This leads to problem on long-running program.
On the other hand, libdrm uses cpu_map_count as a refcount and expects
its value to decrease so it can unmap buffers.
The previoulsy proprosed fix (https://patchwork.freedesktop.org/patch/258005/)
stopped increased the counter when it went past INT_MAX.
This commit instead proposes to use a larger type to store cpu_map_count.
The outcome is the same: long running apps will not crash, only the
implementation differs.
