netdev: fold name hash properly (v3)
The full_name_hash function does not produce well distributed values in
the lower bits, so most code uses hash_32() to fold it. This is really
a bug introduced when name hashing was added, back in 2.5 when I added
name hashing.
hash_32 is all that is needed since full_name_hash returns unsigned int
which is only 32 bits on 64 bit platforms.
Also, there is no point in using hash_32 on ifindex, because the is naturally
sequential and usually well distributed.
