[PATCH v2 3/3] perf sched: Free subcommand string after perf sched stats

[Namhyung Kim <namhyung@kernel.org>]

The first entry of the sched_usage is dynamically allocated in
parse_options_subcommand() so it should be released at the end.
Do not return from a subcommand directly.

Fixes: 064790a3d4a8 ("perf sched stats: Add support for diff subcommand")
