vfio/container: preserve descriptors
At vfio creation time, save the value of vfio container, group, and device descriptors in CPR state. On qemu restart, vfio_realize() finds and uses the saved descriptors. During reuse, device and iommu state is already configured, so operations in vfio_realize that would modify the configuration, such as vfio ioctl's, are skipped. The result is that vfio_realize constructs qemu data structures that reflect the current state of the device.
