rpc: Fixed ping timer algo.

The purpose of the ping timer is to assert the absence of any evidence
the server is possibly alive.

The current implementation updates the 'last_sent' timer in the following
points in time,
- rpc_clnt_submit: when rpc messages are being queued at the transport
  layer. (wrong!, since we have no way to determine if server actually
  received the message)
- rpc_clnt_notify: when client receives pollout event on sending a message
  on the 'wire'. (correct, since it indicates ACK from server)

The fix removes the 'incorrect' update of 'last_sent'.
