Arnaldo Carvalho de Melo 3f6a74bd62 perf evsel: Free evsel->filter on the destructor
Noticed with:

  make EXTRA_CFLAGS="-fsanitize=address" BUILD_BPF_SKEL=1 CORESIGHT=1 O=/tmp/build/perf-tools-next -C tools/perf install-bin

Direct leak of 45 byte(s) in 1 object(s) allocated from:

Free it on evsel__exit().
