[PATCH 2/3] [media] hdpvr: Improve a size determination in hdpvr_alloc_buffers()

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.
