The `COMEDI_BUFINFO` ioctl is used to advance the current position in the buffer by a specified amount (which can be 0) and get the current position. An asynchronous command in the "read" direction is terminated automatically once it has stopped and information about the final position and error has been reported back to the user. That is not currently done for commands in the "write" direction. Change it to terminate the command in the "write" direction automatically. If the command stopped with an error, report an `EPIPE` error back to the user, otherwise just report the final buffer position back to the user.
