RDMA/mlx5: Fix vport loopback forcing for MPV device

Browse source

[ Upstream commit 08aae78604 ]

Previously loopback for MPV was supposed to be permanently enabled,
however other driver flows were able to over-ride that configuration and
disable it.

Add force_lb parameter that indicates that loopback should always be
enabled which prevents all other driver flows from disabling it.
