    If we hit a read error while recovering a mirror, we want to abort the
    recovery without necessarily failing the disk - as having a disk this
    a read error is better than not having an array at all.
    
    Currently this is managed with a per-array flag "recovery_disabled"
    and is only implemented for RAID1.  For RAID10 we will need finer
    grained control as we might want to disable recovery for individual
    devices separately.
    
    So push more of the decision making into the personality.
    'recovery_disabled' is now a 'cookie' which is copied when the
    personality want to disable recovery and is changed when a device is
    added to the array as this is used as a trigger to 'try recovery
    again'.
    
    This will allow RAID10 to get the control that it needs.
