[PATCH v2] net/memif: default to physical socket

[Nathan Skrzypczak <nathan.skrzypczak@gmail.com>]

This patch changes the default value of the memif abstract
socket flag to false. The implementation of memif with
abstract sockets made abstract-socket=yes the
default in [0] which might confuse users.

This patches makes 'socket-abstract=no' the new default,
and adds warnings mentioning the nature of the socket
concerned in an attempt to avoid future foot-gunning.

[0] commit 2f865ed07bb6 ("net/memif: use abstract socket address")
