[PATCH 02/15] md-cluster: Improve another size determination in resync_info_update()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 1 Oct 2016 11:37:24 +0200

Replace the specification of a data structure by a variable name
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer.
