[PATCH 18/54] perf evlist: Do not pass struct record_opts to perf_evlist__prepare_workload()

[Arnaldo Carvalho de Melo]

From: Namhyung Kim <namhyung.kim@xxxxxxx>

Since it's only used for checking ->pipe_output, we can pass the result
directly.

Now the perf_evlist__prepare_workload() don't have a dependency of
struct perf_record_opts, it can be called from other places like perf
stat.
