Subject: [PATCH 2/2 v2] Staging: comedi: addi-data: remove unnecessary variable initializations in hwdrv_apci1564.c

A handful of variables here were being initialized to 0 upon declaration,
however they are always then set to another value before their first use,
so initialization here is useless and we can remove it.
