Ensure that a bonded slave device is not detached,
until it is removed from the bonded device.
Fixes: 2efb58cbab6e ("bond: new link bonding library")
Fixes: a45b288ef21a ("bond: support link status polling")
Fixes: 494adb7f63f2 ("ethdev: add device fields from PCI layer")
Fixes: b1fb53a39d88 ("ethdev: remove some PCI specific handling")
