Rename VFIO_DEVICE_STATE_XXXX defines as VFIO_DEVICE_STATE_V1_XXXX.
Upstream renamed these variable to be of the XXXX_V1_XXXX format and
switched an enum for VFIO_DEVICE_STATE_XXXX.

As we are now pure userspace, there is no need for us to use non-standard
integer types. This leaves the copied defines from Linux's vfio.h alone,
