[media] gspca - kinect: move communications buffers out of stack 

Move large communications buffers out of stack and into device
structure. This prevents the frame size from being >1kB and fixes a
compiler warning when CONFIG_FRAME_WARN=1024:

drivers/media/video/gspca/kinect.c: In function ‘send_cmd.clone.0’:
drivers/media/video/gspca/kinect.c:202: warning: the frame size of 1548 bytes is larger than 1024 bytes
