dm raid: fix nosync status

Browse Source 
Fix a race for "nosync" activations providing "aa.." device health
characters and "0/N" sync ratio rather than "AA..." and "N/N".  Occurs
when status for the raid set is retrieved during resume before the MD
sync thread starts and clears the MD_RECOVERY_NEEDED flag.
