dm raid: fix nosync status
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. Cc: stable@vger.kernel.org # 4.16+ Signed-off-by: Heinz Mauelshagen <heinzm@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
