Jiri Olsa 199abfab40 tracing, function_graph: Remove lock-depth from latency trace
The lock_depth was removed in commit
e6e1e25 tracing: Remove lock_depth from event entry

Removing the lock_depth info from function_graph latency header.

With following commands:
	# echo function_graph > ./current_tracer
	# echo 1 > options/latency-format
	# cat trace

This is what it looked like before:
# tracer: function_graph
#
# function_graph latency trace v1.1.5 on 3.0.0-rc1-tip+
# --------------------------------------------------------------------
# latency: 0 us, #59756/311298, CPU#0 | (M:preempt VP:0, KP:0, SP:0 HP:0 #P:2)
#    -----------------
#    | task: -0 (uid:0 nice:0 policy:0 rt_prio:0)
#    -----------------
#
#      _-----=> irqs-off
#     / _----=> need-resched

 0)  ....  0.068 us    |    } /* __rcu_read_unlock */
...

This is what it looks like now:
# tracer: function_graph
#
# function_graph latency trace v1.1.5 on 3.0.0-rc1-tip+
# --------------------------------------------------------------------
