Subject: [PATCH 2/3] RDS: IB: Improve a size determination in rds_ib_add_one()

From: Markus Elfring <elfring@...rs.sourceforge.net>

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
