sunrpc: Re-purpose trace_svc_process
Currently, trace_svc_process has two call sites:
1. Just after a call to svc_send. svc_send already invokes
trace_svc_send with the same arguments just before returning
2. Just before a call to svc_drop. svc_drop already invokes
trace_svc_drop with the same arguments just after it is called
Therefore trace_svc_process does not provide any additional
information not already provided by these other trace points.
However, it would be useful to record the incoming RPC procedure.
So reuse trace_svc_process for this purpose.
