[media] pvrusb2-io: Use kmalloc_array() in pvr2_stream_buffer_count()
A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software.
