flowprobe: fix accumulation of tcp flags in flow entries
Currently, TCP flags of a flow entry don't get reset once the flow is exported (unlike other meta information about a flow - packet delta count and octet delta count). So TCP flags are accumulated as long as the flow is active. When the flow expires, it is exported the last time, and its pool entry is freed for further reuse. The next flow that gets this pool entry will already have non-zero TCP flags. If it's a TCP flow, the flags will keep being accumulated. This might look fine when exported. If it's a non-TCP flow, that will definitely look erroneous. With this fix, reset TCP flags once the flow is exported. Also, cover the reuse case with tests.
