flowprobe: fix clearing interface state on feature disabling
As a result of recent fixes, all currently stored flows of an interface
are deleted when the feature is being disabled for the interface. This
includes stopping the timer and freeing the flow entries for further
reuse. The problem is that meta information is not cleared in the flow
entries being deleted. For example, packet delta count will keep its
value. The next flow that gets one of these pool entries will already
have a non-zero packet count. So the counting of packets will start from
a non-zero value. And incorrect packet delta count will be exported for
that flow.
With this fix, clear meta information too when clearing interface state.
Also, update the corresponding test to cover this case.
Type: fix
