ipv4: fix ip header ident selection in __ip_make_skb()
Christian Casteyde reported a kmemcheck 32-bit read from uninitialized memory in __ip_select_ident(). It turns out that __ip_make_skb() called ip_select_ident() before properly initializing iph->daddr. This is a bug uncovered by commit 1d861aa4 (inet: Minimize use of cached route inetpeer.)
