Ziyang Xuan 32a5a13d55 ipv4: Fix potential uninit variable access bug in __ip_make_skb()
[ Upstream commit 99e5acae19 ]

Like commit ea30388bae ("ipv6: Fix an uninit variable access bug in
__ip6_make_skb()"). icmphdr does not in skb linear region under the
scenario of SOCK_RAW socket. Access icmp_hdr(skb)->type directly will
trigger the uninit variable access bug.

Use a local variable icmp_type to carry the correct value in different
scenarios.

Fixes: 96793b4825 ("[IPV4]: Add ICMPMsgStats MIB (RFC 4293)")
