ipv4: Add a socket release callback for datagram sockets
[ Upstream commit 8141ed9fcedb278f4a3a78680591bef1e55f75fb ]
This implements a socket release callback function to check
if the socket cached route got invalid during the time
we owned the socket. The function is used from udp, raw
and ping sockets.
