V4L/DVB (13119): gspca - pac7311: remove magic value for USB_BUF_SZ
The length check in reg_w_var() function is because the buffer contents is copied to gspca_dev->usb_buf which has the size of USB_BUF_SZ bytes as defined in drivers/media/video/gspca/gspca.h. Replace the number with symbol for better readability and maintainability.
