[PATCH 2/2] mtd/maps/sun_uflash: Improve a size determination in uflash_devinit()

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.

This issue was detected by using the Coccinelle software.
