vfio/iommufd: invariant device name
cpr-transfer will use the device name as a key to find the value of the device descriptor in new QEMU. However, if the descriptor number is specified by a command-line fd parameter, then vfio_device_get_name creates a name that includes the fd number. This causes a chicken-and-egg problem: new QEMU must know the fd number to construct a name to find the fd number. To fix, create an invariant name based on the id command-line parameter, if id is defined. The user will need to provide such an id to use CPR.
