heal: Pass scan mode to HealObjects to deep scan full quorum objects (#9159)
As an optimization of the healing, HealObjects() avoid sending an
object to the background healing subsystem when the object is
present in all disks.

However, HealObjects() should have checked the scan type, if this
deep, always pass the object to the healing subsystem.
