V4L/DVB (13417): Fix videobuf_queue_vmalloc_init() prototype

For whatever reason, the device structure pointer to
videobuf_queue_vmalloc_init is typed "void *", even though it's passed
right through to videobuf_queue_core_init(), which expects a struct
device pointer.  The other videobuf implementations use struct device *;
I think vmalloc should too.
