staging: comedi: addi_apci_1032: fix i_APCI1032_ReadMoreDigitalInput()

This function is the insn_bits operation for the digital input subdevice.
According to the comedi API it's supposed return the status of the inputs
in data[1]. The addi-drivers abuse the API and try to make it conform to
their own use.

Fix this function so it follows the comedi API.
