[media] kinect: fix sparse warnings

drivers/media/usb/gspca/kinect.c:151:19: warning: incorrect type in assignment (different base types)

drivers/media/usb/gspca/kinect.c:153:19: warning: incorrect type in assignment (different base types)
drivers/media/usb/gspca/kinect.c:191:13: warning: restricted __le16 degrades to integer

drivers/media/usb/gspca/kinect.c:218:16: warning: incorrect type in assignment (different base types)

Note that this fixes a real bug where cpu_to_le16 was used instead of the correct
le16_to_cpu.
