dvsource-alsa: Fix placement of VS and VSC packs

We used the correct block numbers for each sequence, but the wrong
pack numbers within those blocks.
Correct the standard cycle of samples per frame for 32 kHz audio

Also update the comment about this member to refer to the table in
the standard.

This helps building dvswitch manually. Not sure why the buildservice does not need this.
