net: bridge: mark hash_elasticity as obsolete
Now that the bridge multicast uses the generic rhashtable interface we
can drop the hash_elasticity option as that is already done for us and
it's hardcoded to a maximum of RHT_ELASTICITY (16 currently). Add a
warning about the obsolete option when the hash_elasticity is set.
