tools lib traceevent: Fix processing of dereferenced args in bprintk events
In the case that a bprintk event has a dereferenced pointer that is stored as a string, and there's more values to process (more args), the arg was not updated to point to the next arg after processing the dereferenced pointer, and it screwed up what was to be displayed.
