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:...
