Fix the used device size in mdadm -D output.

As get_component_size() returns the number of used sectors of a device
we need halve before pringing as K, and shift the value by 9, not 10,
before passing to human_size.

Thanks to Andre Noll <maan@systemlinux.org> for identifying problem
(and a slightly different version of this patch)
