net/appletalk: fix minor pointer leak to userspace in SIOCFINDIPDDPRT
[ Upstream commit 9824dfae5741275473a23a7ed5756c7b6efacc9d ]
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().
