[PATCH v3 6/7] perf config: Remove needless code about config set at cmd_config()

[Taeung Song]

show_config() was reimplemented using perf_config()
so it isn't needed to use perf_config_set__new() at cmd_config().
And perf_config_set__delete() isn't needed at cmd_config() because of
calling the function at run_builtin() when a sub-command finished.

And it isn't also needed to declare 'config_set' as extern variable
because the variable is only handled at util/config.c from now on.
