Namhyung Kim da45c8d5f0 perf/core: Simplify __detach_global_ctx_data() ...

Like in the attach_global_ctx_data() it has a O(N^2) loop to delete task
context data for each thread.  But perf_free_ctx_data_rcu() can be
called under RCU read lock, so just calls it directly rather than
iterating the whole thread list again.
