md/raid6: Fix raid-6 read-error correction in degraded state
commit 87aa63000c484bfb9909989316f615240dfee018 upstream.
Fix: Raid-6 was not trying to correct a read-error when in
singly-degraded state and was instead dropping one more device, going to
doubly-degraded state. This patch fixes this behaviour.
