Remove Spare drives line from details for external metadata

Arrays with external metadata do not have spare disks directly
assigned to volumes; spare disks belong to containers and are
moved to arrays when the array is degraded/reshaping.
Thus, the display of zero spare disks in volume details is
incorrect and can be confusing.
