staging: comedi: addi_apci_1032: Fix endian problem for COS sample
The Change-Of-State (COS) subdevice supports Comedi asynchronous
commands to read 16-bit change-of-state values. However, the interrupt
handler is calling `comedi_buf_write_samples()` with the address of a
32-bit integer `&s->state`. On bigendian architectures, it will copy 2
bytes from the wrong end of the 32-bit integer. Fix it by transferring
the value via a 16-bit integer.
Fixes: 6bb45f2b0c86 ("staging: comedi: addi_apci_1032: use comedi_buf_write_samples()")
