From: Andi Kleen <ak@linux.intel.com>
Fix the logic to allow overriding event default periods with -c or -F on the command line. I'm not sure I understand this if() fully, but this change makes all cases I tested work (tracepoint with default, default, ,-c, -F)
This fixed specifying -c / -F with json event list events, which have a default period. It should do the same for trace point events.
