hash: add local variable
The current implmentation of the hash table is not thread-safe.
This design leads to a segfault when VPP handling a lot of tunnels for
Wireguard, where one thread modify the hash table and other threads
starting to lookup at the same time.
The fix add a local variable to store how many bits are used by a user
object.
Type: fix
