drbd: fix regression: attach while connected failed
commit e4f925e12ea5daaa9baf2dd5af9c4951721dae95
Author: Philipp Reisner <philipp.reisner@linbit.com>
Date: Wed Mar 17 14:18:41 2010 +0100
drbd: Do not upgrade state to Outdated if already Inconsistent
prevented the necessary state transition for attaching while connected
(Diskless -> Consistent respectively Outdated).
This is the fix for the fix.
