Subject: [PATCH 08/13] DRBD-receiver: Move an assignment in receive_sizes()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 10 Sep 2016 21:50:18 +0200

Move one assignment for the local variable "ldsc" so that its setting
will only be performed after corresponding data processing succeeded
by this function.
