staging: comedi: adl_pci9118: handle error detection in main interrupt handler

The DMA and non-DMA both check the analog input status value to detect
hardware errors. For aesthetics, move the this detection into the main
interrupt handler. This allows removing the unused 'int_adstat' parameter
from the  DMA and non-DMA handlers. In addition, the 'int_daq' parameter
is also not used so remove it also.
