cluster/ec: Fix write size in self-heal
Self-heal was always using a fixed block size to heal a file. This was incorrect for dispersed volumes with a number of data bricks not being a power of 2. This patch adjusts the block size to a multiple of the stripe size of the volume. It also propagates errors detected during the data heal to stop healing the file and not mark it as healed.
