samples: net: sockets: coap_download: Cancel requests before closing

Browse source 
Call coap_client_cancel_requests() before closing the client socket so
that all activities on that socket are ceased before close. This
prevents POLLNVAL error from being thrown by the coap_client thread and
error being printed in the sample output.
