[Qemu-stable] [PATCH] vfio/pci: Default display option to "off"

[Alex Williamson]

Commit a9994687cb9b ("vfio/display: core & wireup") added display
support to vfio-pci with the default being "auto", which breaks
existing VMs when the vGPU requires GL support but had no previous
requirement for a GL compatible configuration.  "Off" is the safer
default as we impose no new requirements to VM configurations.
