tools lib traceevent: No need to check for < 0 on an unsigned enum
gcc on f14 32-bit complains:
tools/lib/traceevent/event-parse.c: In function ‘pevent_register_print_function’:
tools/lib/traceevent/event-parse.c:5366:3: error: comparison of unsigned expression < 0 is always false
This is because:
enum pevent_func_arg_type type;
this enum doesn't have any negative value, so gcc makes it an 'unsigned
int'. Fix it by removing the < 0 test.
