mxfenc: explicitly truncate continuity count.
The field is intended to overflow and have only its low 16bits stored.
This commit avoids the implicit truncation and clarifies that its
intended and not a bug
S326m section 7.6 ("Continuity count"):
> The continuity count word consists of 2 bytes allow-
> ing a number to be created by a modulo 65536
> counter (bits C15 to C0 in figure 7). The continuity
> count shall increment by 1 for each newly transmit-
> ted content package with the same SDTI source and
> destination addresses. The continuity count may
> be used to detect whether the content package
> sequence has been broken by an operation such as
> a routing switch.
