Return an error from cs_dsp_power_up() if a block header is longer
than the amount of data left in the file.
The previous code in cs_dsp_load() and cs_dsp_load_coeff() would loop
while there was enough data left in the file for a valid region. This
protected against overrunning the end of the file data, but it didn't
abort the file processing with an error.
