2.6.32-stable review patch. If anyone has any objections, please let us know.

------------------

From: Gabriele A. Trombetti <g.trombetti.lkrnl1213(a)logicschema.com>

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.
