Revert "staging: comedi: cb_pcidas64: change params to external_ai_queue_in_use()"
This reverts commit f5f3a2c6 ("staging: comedi: cb_pcidas64: change params to external_ai_queue_in_use()"). The `external_ai_queue_in_use()` was being called from `ao_cmd()` with pointers to the "write" subdevice and AO command, but is supposed to check whether the external AI queue is currently in use by the "read" subdevice and AI command. In fact, the return value always indicated that the external AI queue was not in use in this case (because the AO command's channel list is sequential), so was fairly useless. (However, even before the reverted commit, the logic in `external_ai_queue_in_use()` was wrong. That will be corrected in a subsequent commit.)
