vfio: Rename VFIODevice related services

Rename these routines :

  vfio_disable_irqindex       -> vfio_device_irq_disable
  vfio_unmask_single_irqindex -> vfio_device_irq_unmask
  vfio_mask_single_irqindex   -> vfio_device_irq_mask
  vfio_set_irq_signaling      -> vfio_device_irq_set_signaling
  vfio_attach_device          -> vfio_device_attach
  vfio_detach_device          -> vfio_device_detach
  vfio_get_region_info        -> vfio_device_get_region_info
  vfio_get_dev_region_info    -> vfio_device_get_region_info_type
  vfio_has_region_cap         -> vfio_device_has_region_cap
  vfio_reset_handler          -> vfio_device_reset_hander

to better reflect the namespace they belong to.
