Actually this clean up of removing the duplicate pevent should have been a
separate patch as well. I'll take this as is (as the patches seem to be
solid), but for the future, try to keep small clean ups like this as
separate patches. One advantage is, if someone is supporting an older
version of trace-cmd, they may want to backport the clean up, but not the
feature.
