dig: always set the default port when doing a UDP query

Browse source 
This commit ensures that the port is set before attempting a UDP
query. Before that a situation could appear when previous query have
completed over a different transport (that uses a dedicated port) and
then a UDP query will be attempted over the port of the previous
transport.
