[PATCH 09/15] perf tools: Continue processing header on unknown features

[Arnaldo Carvalho de Melo]

From: Robert Richter <robert.richter@xxxxxxx>

A feature may be unknown if perf.data is created and parsed on different
perf tool versions. This should not stop the header to be processed,
instead continue processing it.
