SUNRPC: task_run_action should display tk_callback
This shows up in every RPC:
kworker/4:1-19772 [004] 3467.373443: rpc_task_run_action: task:4711@2 flags=0e81 state=0005 status=0 action=call_status
kworker/4:1-19772 [004] 3467.373444: rpc_task_run_action: task:4711@2 flags=0e81 state=0005 status=0 action=call_status
What's actually going on is that the first iteration of the RPC
scheduler is invoking the function in tk_callback (in this case,
xprt_timer), then invoking call_status on the next iteration.
Feeding do_action, rather than tk_action, to the "task_run_action"
trace point will now always display the correct FSM step.
