V4L/DVB (13716): [Mantis] Bug: incorrect byte swap

You know, the worst endianness errors are not the cases where
people forget to byte-swap, but the cases where they either byte-swap
with the wrong size, or byte-swap when they shouldn't have done so at
all. Those ones defeat the casual reader of the code.
