Subject: [PATCH 1/2 v2] perf intel-pt/bts: remove unused SAMPLE_SIZE defines
 and bts priv array

These defines were probably dragged in from sampling support in earlier
patches.  They can be put back when needed.

v2: addressed Ingo's comment by populating changelog with Adrian's
explanation of why they were unused
