Vinicius Costa Gomes 270673e112 samples/zoap_client: Fix using the wrong timeout for retransmissions
It was assumed that the unit was microseconds, it is in miliseconds,
the same unit that is stored in the timeout field of the pending
transmission.

CoAP client
###########

Overview
********

A simple CoAP server showing how to retrieve information from a resource.

This demo assumes that the platform of choice has networking support,
some adjustments to the configuration may be needed.

This sample will make a GET request with path 'test' to the IPv6
multicast address reserved for CoAP nodes, so the URI can be
represented as:

.. code-block:: none

    coap://[ff02::fd]:5683/test

Building and Running
********************

This project will print all the octets of the response received, more context can
be obtained by using a tool like tcpdump or wireshark.

See the `net-tools`_ project for more details.

It can be built and executed on QEMU as follows:

.. code-block:: console

    make run

Sample output
=============

.. code-block:: console
