flow: New function flow_unwildcard_tp_ports().

Browse Source 
This patch adds a new function flow_unildcard_tp_ports() which doesn't
unwildcard the upper half of tp_src and tp_dst with ICMP packets.
Unfortunately, this matters in future patches when we compare masks
carefully to determine if flows should be evicted from the datapath.
