perf tools: Fix proper buffer size for feature processing
After Song Liu's segfault fix for pipe mode, Arnaldo reported following
error:
# perf record -o - | perf script
0x514 [0x1ac]: failed to process type: 80
It's caused by wrong buffer size setup in feature processing, which
makes cpu topology feature fail, because it's using buffer size to
recognize its header version.
