03616af2c9 Revert "takdec: pad filter coeff buffer for DSP functions" 
This reverts commit e0c7ba40cf0bb521430f4a808ed1f1a408093f9c.

Valgrind complains about invalid reads, which generate segfaults in some
systems.

e0c7ba40cf takdec: pad filter coeff buffer for DSP functions 
Currently, a part of the loop has to be handled in plain C, because of DSP
function requirements of having batches of 16 elements to process.

Instead, pad the buffer with 0 where the DSP functions are overreading.
