vfio: unhide vdev->debug_root
When debugfs is disabled, the hisilicon driver now fails to build:
drivers/vfio/pci/hisilicon/hisi_acc_vfio_pci.c: In function 'hisi_acc_vfio_debug_init':
drivers/vfio/pci/hisilicon/hisi_acc_vfio_pci.c:1671:62: error: 'struct vfio_device' has no member named 'debug_root'
1671 | vfio_dev_migration = debugfs_lookup("migration", vdev->debug_root);
| ^~
The driver otherwise relies on dead-code elimination, but this reference
fails. The single struct member is not going to make much of a difference
for memory consumption, so just keep this visible unconditionally.
