Steven Rostedt (Red Hat) ef92480a58 tracing: Turn seq_print_user_ip() into a static function
seq_print_user_ip() is used in only one location in one file. Turn it into a
static function. We could inject its code into the caller, but that would
make the code a bit too complex. Keep the code separate.
