Bug fix: invalid name of devices

[zyronix]

On some platforms PCI devices can become nested, this causes there to be one more column in the device name.

Example:

72:00:0000.0 VGA compatible controller: NVIDIA Corporation TU104 [GeForce RTX 2080] (rev a1)

# versus:

72:00.0 VGA compatible controller: NVIDIA Corporation TU104 [GeForce RTX 2080] (rev a1)

This will mark the device as a VGA compatible controller and not as NVIDIA Corporation TU104 [GeForce RTX 2080] (rev a1)

This pull requests fixes that.
