[NETNS]: Lookup in FIB semantic hashes taking into account the namespace.
The namespace is not available in the fib_sync_down_addr, add it as a
parameter.
Looking up a device by the pointer to it is OK. Looking up using a
result from fib_trie/fib_hash table lookup is also safe. No need to
fix that at all. So, just fix lookup by address and insertion to the
hash table path.
