ckeckbox filter out the part of "Graphic card" when generate test plan

Can you provide the CID for this device?

We recently introduced a change to filter unnecessary graphics jobs when running devices with specific hardware (see lp:1636060) so it might not be a bug but a feature :)

CID is 201610-25146.

We found this symptom would be observed on some graphic cards in the same device includes Nvidia & AMD.
So far it occurred on graphic cards AMD W4100, AMD W5100 & Nvidia M2000

This symptom also observed on Matira platform

1. SKU: MA5-DVT1-C2(201612-25266), MA7-DVT1-C1(201612-25310)
2. BIOS: 0.3.7
3. Manifest: dell-bto-xenial-pearl-X40-iso-20161202-0
4. Failed rate: 10/10
5. graphic_card_resouce would crash when generate test plan

Thanks to Scott for showing me a device with those symptoms.
(it's a server using desktop Ubuntu image)

Current situation
-----------------

$ ./graphics_card_resource -c ./udev_resource
Traceback (most recent call last):
  File "./graphics_card_resource", line 168, in <module>
    raise SystemExit(main())
  File "./graphics_card_resource", line 122, in main
    video_devices.sort(key=lambda r: bus_ordering(r))
  File "./graphics_card_resource", line 122, in <lambda>
    video_devices.sort(key=lambda r: bus_ordering(r))
  File "./graphics_card_resource", line 97, in bus_ordering
    return int(record.get('path').split(':')[-2])
ValueError: invalid literal for int() with base 10: 'b3'

Root cause
----------

So far, the digit extracted by bus_ordering() had always been a base 10 integer.
However, on servers, the extracted digit looks more like an hexadecimal value (base 16 integer):

/devices/pci0000:b2/0000:b2:00.0/0000:b3:00.0

Solution
--------

In /usr/lib/plainbox-provider-resource-generic/bin/graphics_card_resource, line 96, replace:

    return int(record.get('path').split(':')[-2])

with:

    return int(record.get('path').split(':')[-2], 16)

Result
------

$ ./graphics_card_resource -c ./udev_resource
bus: pci
category: VIDEO
driver: nvidia
index: 1
path: /devices/pci0000:b2/0000:b2:00.0/0000:b3:00.0

This change should not create regression, but it has to be confirmed by testing on a laptop/desktop before pushing to stable.
