md/raid10 - support resizing some RAID10 arrays.
'resizing' an array in this context means making use of extra space that has become available in component devices, not adding new devices. It also includes shrinking the array to take up less space of component devices. This is not supported for array with a 'far' layout. However for 'near' and 'offset' layout arrays, adding and removing space at the end of the devices is easy to support, and this patch provides that support. Signed-off-by: NeilBrown <neilb@suse.de>
