Subject: [PATCH 05/13] DRBD-receiver: Delete an unnecessary initialisation in
 receive_sizes()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 10 Sep 2016 20:04:02 +0200

A local variable was assigned a null pointer despite of the detail
that it was immediately reassigned by the following statement.
Thus remove such an unnecessary initialisation.
