[igt-dev] [PATCH i-g-t 20/21] lib/igt_x86: Mock-use variable to silence static analysis

[Petri Latvala]

x86_features_to_string() uses a repeatable pattern that increments a
pointer for each feature string, leaving a dead assignment for the
last one. Add a (void)line to the end just to silence static analysis.
