Subject: [ 078/102] drbd: fix memory leak

3.9-stable review patch.  If anyone has any objections, please let me know.

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

From: Lars Ellenberg <lars.ellenberg@...bit.com>

commit 94ad0a101415978be04945b2787be1e8e8a874db upstream.

We forgot to free the disk_conf,
so for each attach/detach cycle we leaked 336 bytes.
