Naming in code comments for tracing_snapshot, tracing_snapshot_alloc
and trace_pid_filter_add_remove_task don't match the real function
names. And latency_trace has been removed from tracing directory.
Fix them.
Fixes: cab5037 ("tracing/ftrace: Enable snapshot function trigger")
Fixes: 886b5b7 ("tracing: remove /debug/tracing/latency_trace")
