[media] dvb-usb: check for invalid length in ttusb_process_muxpack()
This patch is driven by a static checker warning.
The ttusb_process_muxpack() function is only called from
ttusb_process_frame(). Before calling, it verifies that len >= 2. The
problem is that len == 2 is not valid and would lead to an array
underflow.
Odd number values for len are also invalid and would lead to reading
past the end of the array.
