In VTN Coordinator UDP L4 match details of source and destination creation fails in Flowlistentry.
It accepts ipproto value as 17 but shows tcp source and destination values in logs.

Steps to reproduce the bug:

1. curl -v --user admin:adminpass -H 'content-type: application/json' -X POST -d '{"controller":{"controller_id": "odc1", "ipaddr":"127.0.0.1", "type": "odc", "version": "1.0", "auditstatus":"enable"}}' http://127.0.0.1:8083/vtn-webapi/controllers

1. curl -v --user admin:adminpass -H 'content-type: application/json' -X POST -d '{"vtn" : {"vtn_name":"vtn1","description":"test VTN" }}' http://127.0.0.1:8083/vtn-webapi/vtns.json

1. curl -v --user admin:adminpass -H 'content-type: application/json' -X POST -d '{"vbridge" : {"vbr_name":"vBridge1","controller_id":"controllerone","domain_id":"(DEFAULT)" }}' http://127.0.0.1:8083/vtn-webapi/vtns/vtn1/vbridges.json

1. curl -v --user admin:adminpass -H 'content-type: application/json' -X POST -d '{"interface": {"if_name": "if1","description": "if_desc1"}}' http://127.0.0.1:8083/vtn-webapi/vtns/vtn1/vbridges/vBridge1/interfaces.json

1. curl -v --user admin:adminpass -H 'content-type: application/json' -X PUT -d '{"portmap":{"logical_port_id": "PP-OF:openflow:72931086629252-veth1_ovs"}}' http://127.0.0.1:8083/vtn-webapi/vtns/vtn1/vbridges/vBridge1/interfaces/if1/portmap

1. curl -v --user admin:adminpass -H 'content-type: application/json' -X POST -d '{"flowlist": {"fl_name": "flowlist1", "ip_version":"IP"}}' http://127.0.0.1:8083/vtn-webapi/flowlists.json

1. curl -v --user admin:adminpass -H 'content-type: application/json' -X POST -d '{"flowlistentry": {"seqnum":"1","ipproto":"17","l4dstport":"400","l4dstendport":"600"}}' http://127.0.0.1:8083/vtn-webapi/flowlists/flowlist1/flowlistentries.json

1. curl -v --user admin:adminpass -X POST -H 'content-type: application/json' -d '{"flowfilter" : {"ff_type": "in"}}' http://127.0.0.1:8083/vtn-webapi/vtns/vtn1/vbridges/vBridge1/interfaces/if1/flowfilters.json

1. curl -v --user admin:adminpass -X POST -H 'content-type: application/json' -d '{"flowfilterentry": {"seqnum": "1", "fl_name": "flowlist1", "action_type":"pass","priority":"1"}}' http://127.0.0.1:8083/vtn-webapi/vtns/vtn1/vbridges/vBridge1/interfaces/if1/flowfilters/in/flowfilterentries.json
