[PATCH v7 02/13] vfio: tolerate migration protocol v1 uapi renames

[Pierre Morel <pmorel@xxxxxxxxxxxxx>]

From: Matthew Rosato <mjrosato@xxxxxxxxxxxxx>

The v1 uapi is deprecated and will be replaced by v2 at some point;
this patch just tolerates the renaming of uapi fields to reflect
v1 / deprecated status.
