lib/igt_device_scan: Skip attributes in subdirectories
Skip reading attributes in subdirectories as they are not used for
filtering. This change improves speed and reduces the impact of
non-DRM related component bugs on testing, such as the ASPM exposed
link/l1_aspm attribute issue. After removing a Virtual Function (VF),
accessing the link/l1_aspm attribute on the Physical Function (PF)
leads to NPD.
v2: removed unrelated changes, improved description (Michal)
