Enable setting of 'offset' and 'size' of a hot-added spare.
offset_store and rdev_size_store allow control of the region of a device which is to be using in an md/raid array. They only allow these values to be set when an array is being assembled, as changing them on an active array could be dangerous. However when adding a spare device to an array, we might need to set the offset and size before starting recovery. So allow these values to be set also if "->raid_disk < 0" which indicates that the device is still a spare. Signed-off-by: Neil Brown <neilb@suse.de>
