  4xm: do not overread the source buffer in decode_p_block

Conflicts:
	libavcodec/4xm.c

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()

This fixes #2657.
ISML movies produced by Microsoft Expression Encoder 4 seem to have invalid
sample entries in their trun/tfhd for data tracks. As a result, too much bytes
are read for these tracks to the point that next_root_atom can go out of
buffer, which makes the encoding fail if the input is not seekable.
