perf python: Fix argument name list of read_on_cpu()
Mandatory arguments need to be present in the argument name list, as well as optional arguments, otherwise python barfs: # ./python/twatch.py Traceback (most recent call last): File "./python/twatch.py", line 41, in <module> main() File "./python/twatch.py", line 32, in main event = evlist.read_on_cpu(cpu) RuntimeError: more argument specifiers than keyword list entries Hence, add cpu to the name list.
