[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.
