Subject: [PATCH] Fix --update-subarray on active volume

Options: bitmap, ppl and name should not be updated when array is active.
Those features are mutually exclusive and share the same data area in IMSM (danger of overwriting by kernel).
Remove check for active subarrays from super-intel.
Since ddf is not supported, apply it globally for all options.
