It's possible to have an evsel and evsel->evlist populated without
an evsel->evlist->env, when, e.g., cmd_record is in its error path.
Future patches will add support for evsel__open_strerror to be able
to customize error messaging based on perf_env__{arch,cpuid}, so
let's have evsel__env return &perf_env instead of NULL in that case.
