[PATCH 05/26] IB/ocrdma: Improve another size determination in ocrdma_mbx_query_qp()

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.
