media: stk1160: Set the vb2_queue lock before calling vb2_queue_init

The vb2_queue will soon be mandatory. The videobuf2 core
will throw a verbose warning if it's not set.

The stk1160 driver is setting the queue lock, but after
the vb2_queue_init call. Avoid the warning by setting
the lock before the queue initialization.
