Description

In a new MinIO version, Healing can be set to false while HealInfo is not nil. This indicates that the drive was healed and the healing is finished. This commit adapts the code with the new concept. This will not break with older MinIO versions since those versions will already remove .healing.bin, in that case Healing will be false, HealInfo will be nil.
