The checks are replaced by av_assert0() as the conditions should
be impossible. If these asserts fail, there is a bug elsewhere

  4xm: drop pointless assert

Conflicts:
	libavcodec/4xm.c

The added condition is impossible to occur and thus is added to the assert.
The assert is not removed from the default case, as the default case cannot
occur. Thus either it should stay as is or the case as a whole be removed.
For extra safety, to ensure this doesnt change the assert is changed to
av_assert0()

3f54547709 utvideo: Add ULH0 and ULH2 decoding to the native decoder.
Also prevents an error since the native decoder (if enabled) is
always used to probe Ut Video-encoded files, even if the user
forces libutvideo to be the decoder. Without this patch, the probe
would fail, and the video wouldn't get properly handed over,
resulting in failure to set codec parameters. When the native
decoder is disabled, libutvideo can probe and initialize decoding
without issues.
