Move dco_installed from sock->info to sock->info.lsa.actual

Move dco_installed from sock->info to sock->info.lsa.actual

For tcp this makes no difference as the remote address of the
socket never changes. For udp this allows OpenVPN to differentiate
if a reconnecting client is using the same address as before or
from a different one. This allow sending via the normal userspace
socket in that case.
