fix bug:external protocols not set to local broker data (apache#5479)

# Motivation

lastData set external protocolData twice, it seems to be a spelling mistake.

### Modifications

  - change the second 'lastData.setProtocols(protocolData);' to '  localData.setProtocols(protocolData);'
  - format relative codes
