ASan reports memory leaks while running the perf test "83: Zstd perf.data compression/decompression". The first of the leaks is caused by env->cpu_pmu_caps not being freed. This patch adds the missing (z)free inside perf_env__exit.
Fixes: 6f91ea283a1ed23e ("perf header: Support CPU PMU capabilities")
Thanks, applied.
