Willy Tarreau 11f734283a net/appletalk: fix minor pointer leak to userspace in SIOCFINDIPDDPRT

[ Upstream commit 9824dfae57 ]

Fields ->dev and ->next of struct ipddp_route may be copied to
userspace on the SIOCFINDIPDDPRT ioctl. This is only accessible
to CAP_NET_ADMIN though. Let's manually copy the relevant fields
instead of using memcpy().
