drbd: Fix state change in case of connection timeout
commit 9581f97a687724ea41cf2e145dda4751161198c1 upstream.
A connection timeout affects all volumes of a resource!
Under the following conditions:
A resource with multiple volumes
AND
ko-count >=1
AND
a write request triggers the timeout (ko-count * timeout)
DRBD's internal state gets confused. That in turn may
lead to very miss leading follow up failures. E.g.
"BUG: scheduling while atomic"
