hlist initilization

Hi Davem,

This patch adds proper initialization for hlist. It applies to af_netlink.c with the workqueue patch reverted.

nl_table[] is in the BSS and therefore will be
properly zero initialized already.

I took advantage of this same property in the
net/ipv4/fib_hash.c changes.
