From: Ilya Pronin <ipro...@twitter.com>
When printing stats in CSV mode, perf stat appends extra CSV
separators when counter is not supported:
<not
supported>,,L1-dcache-store-misses,mesos/bd442f34-2b4a-47df-b966-9b281f9f56fc,0,100.00,,,,
which causes a failure of parsing fields. The numbers of separators
is fixed for each line, no matter supported or not supported.
Fixes: 92a61f6412d3 ("perf stat: Implement CSV metrics output")
