vfio/pds: Send type for SUSPEND_STATUS command
Commit bb500dbe2ac6 ("vfio/pds: Add VFIO live migration support")
added live migration support for the pds-vfio-pci driver. When
sending the SUSPEND command to the device, the driver sets the
type of suspend (i.e. P2P or FULL). However, the driver isn't
sending the type of suspend for the SUSPEND_STATUS command, which
will result in failures. Fix this by also sending the suspend type
in the SUSPEND_STATUS command.
