Handle un-readable kfd properties files

Browse Source 
Some systems have kfd sysfs properties entries that
are unreadable--for example, when a multi-gpu system is
dividing the gpus among containers, each container may
only be able to access certain gpus.

Previously, all kfd topology node properties entries were
assumed to be valid. Now, we check for readability before
declaring them "valid".

Fixes SWDEV-240169

Also:
* remove an assertion that would happen when no pcie
device identifier files are found on the system.
* fix cpplint issues
