[PATCH] trace-cmd list: Show parameters of all functions if specified

From: "Steven Rostedt (Google)" <[email protected]>

Currently "trace-cmd list --proto -f" just dumps the functions without
showing the arguments for them. That's because if "-f" is used without a
parameter the code just dumps the contents of "available_filter_functions".

Have it still show the parameters if --proto is specified with just "-f".
