tracing: Don't add flag strings when displaying variable references
Variable references should never have flags appended when displayed - prevent that from happening. Before: # cat /sys/kernel/debug/tracing/events/sched/sched_switch/trigger hist:keys=next_pid:vals=hitcount:wakeup_lat=common_timestamp.usecs-$ts0.usecs:... After: hist:keys=next_pid:vals=hitcount:wakeup_lat=common_timestamp.usecs-$ts0:...
