tuntap: limit the number of flow caches
We create new flow caches when a new flow is identified by tuntap, This may lead
some issues:
- userspace may produce a huge amount of short live flows to exhaust host memory
- the unlimited number of flow caches may produce a long list which increase the
time in the linear searching
Solve this by introducing a limit of total number of flow caches.
