Herbert Xu c428ecd1a2 netlink: Move namespace into hash key
Currently the name space is a de facto key because it has to match
before we find an object in the hash table.  However, it isn't in
the hash value so all objects from different name spaces with the
same port ID hash to the same bucket.

This is bad as the number of name spaces is unbounded.

This patch fixes this by using the namespace when doing the hash.

Because the namespace field doesn't lie next to the portid field
in the netlink socket, this patch switches over to the rhashtable
interface without a fixed key.

This patch also uses the new inlined rhashtable interface where
possible.
