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:...
