Bug 2442 - UDP matching flow adds a match on dst port=0 (only occurs with OF10)
Existing code was incorrectly setting the wildcard flag for source port and destination port.
It was setting the flag if user specified source/destination IP address in match, so even if
user did not specified source/destination port, flag is getting set and thats why switch
thinks that port is not wildcarded and it set the port to default short value (0).
