perf env: Fix memory leak of cpu_pmu_caps
[ Upstream commit da6b7c6c0626901428245f65712385805e42eba6 ]
ASan reports memory leaks while running:
# 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.
