Luca Barbato 79f64f7ebc bitstream: Avoid undefined behavior in bitstream_skip() ...

Do not use skip_remaining() to fully wipe the cache, as this could do
a 64-bit shift of a 64-bit variable which is undefined behavior in C.
Instead set the related variables to zero directly.

Thanks to Uoti for pointing out the problem.
