Fix OVPN_DEL_PEER_REASON_TRANSPORT_DISCONNECT breakage on FreeBSD+DCO

commit 67c4eebdae introduces a new peer disconnect reason (transport
disconnected, aka "TCP session closed") which breaks compilation on
FreeBSD - OVPN_DEL_PEER_REASON_TRANSPORT_DISCONNECT not part of the
enum in freebsd_dco.h, and no kernel support for TCP anyway.

This patch is an intermediate bandaid, making the offending code in
multi.c "linux only" while a better solution is discussed.
