[PATCH 5.13 058/223] perf env: Fix memory leak of cpu_pmu_caps

[Greg Kroah-Hartman]

From: Riccardo Mancini <rickyman7@xxxxxxxxx>

[ 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.
