[igt-dev] [PATCH i-g-t] tests/kms_frontbuffer_tracking: Accept missing FBC debugfs files

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

With multiple FBC instances becoming a thing at some point
the current plan is to go with separate debugfs files for
each FBC instance. Which also means that if there is no
FBC there will be no debugfs files either. Adapt the test
to tolerate such conditions.
