disk_list_get() can return NULL if:
1/ A formerly missing disk is re-added
2/ The original array has not been rebuilt, so the family number of the
missing disk still matches
3/ The metadata record of the in-sync disks are read before the missing
disk
This will result in the missing disk not adding its own serial number to
the disk_list, only its truncated value will be present.
