There appears to be a mismatch between increase flow_memuse when allocating a new flow and decrementing it when freeing the flow.

In flow-util.c:

FlowAlloc() adds sizeof(Flow) + FlowStorageSize() to flow_memuse
FlowFree() subtracts sizeof(Flow)

So for each flow created and destroyed, flowmemcap incorrectly is larger by FlowStorageSize()
