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 1d861aa4b3fb (inet: Minimize use of
cached route inetpeer.)
