netutils/libcoap : patch for coap_transaction_id function

This commit is patch to coap_transaction_id function
problem
 - coap_hash function uses structure addr.sa to create tid
 - when coap message is received,
   tid, which is in received coap message, is used to
   comparing sender's tid
 - unmatched case occurs, when addr.sa is used to create tid
 - in this case, sender cannot find coap response message
   which has same tid of sender so infinite retransmission
   happens on application
 solution
 - uses addr and port value to create tid similar to IPv6
