ip: fix wrong radix for iphash() (thanks yoann padioleau)
yoann padioleaus report on 9fans:
> I think I’ve found a bug in the network stack.

> iphash(uchar *sa, ushort sp, uchar *da, ushort dp)
> {
> return ((sa[IPaddrlen-1]<<24) ^ (sp << 16) ^ (da[IPaddrlen-1]<<8) ^ dp ) % Nhash;
> }

> where Nhash is just 64,
