flowcache: Fix resource leaks on namespace exit.
We leak an active timer, the hotcpu notifier and all allocated
resources when we exit a namespace. Fix this by introducing a
flow_cache_fini() function where we release the resources before
we exit.
Fixes: ca925cf1534e ("flowcache: Make flow cache name space aware")
