ftrace: Return NULL at end of t_start() instead of calling t_hash_start()
The loop in t_start() of calling t_next() will call t_hash_start() if the pos is beyond the functions and enters the hash items. There's no reason to check if p is NULL and call t_hash_start(), as that would be redundant. Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
