ipv4: raw: Fix sending packets from raw sockets via IPsec tunnels
[ Upstream commit c9b3b81716c5b92132a6c1d4ac3c48a7b44082ab ]
Since the referenced commit, the xfrm_inner_extract_output() function
uses the protocol field to determine the address family. So not setting
it for IPv4 raw sockets meant that such packets couldn't be tunneled via
IPsec anymore.
IPv6 raw sockets are not affected as they already set the protocol since
9c9c9ad5fae7 ("ipv6: set skb->protocol on tcp, raw and ip6_append_data
genereated skbs").
Fixes: f4796398f21b ("xfrm: Remove inner/outer modes from output path")
