[PATCH v2 3/5] perf config: Modify perf_config_set__delete() using global variable 'config_set'

[Taeung Song <treeze.taeung@gmail.com>]

This function deleted allocated config set but
the global variable 'config_set' is used all around
so this directly remove 'config_set' instead of using local variable 'set'.
