updateConnection operation should use POST(CoAP) method

[wukaishanda08]

In file lwm2m-client.js

function updateRegistration(deviceInformation, callback) {
var rs = new Readable(),
creationRequest = {
host: deviceInformation.currentHost,
port: deviceInformation.currentPort,
method: 'PUT',
pathname: deviceInformation.location,
query: 'lt=' + config.client.lifetime + '&lwm2m=' + config.client.version + '&b=U'
},

The method "PUT" should be "POST". There is no log while updateConnection use PUT. But the console outputs the right log while use POST

The lwm2m-server.js recieve POST method, so as the LWM2M Document.

serverInfo.routes = [
    ['POST', /^\/rd$/, 'registration'],
    ['DELETE', /\/rd\/.*/, 'unregistration'],
    ['POST', /\/rd\/.*/, 'updateRegistration']
];
