Upon md device creation, component devices are sometimes removed
immediately again due to a "disk failure". The disks seem healthy,
though. This patch re-adds compoenent devices in such cases to
prevent that the md device will remain in a degraded state (which
would cause issues later, e.g. during ESP creation).
