staging: comedi: das800: tidy up das800_interrupt()

Rename the CamelCase variable 'dataPoint'.

Cleanup some of the comments and fix the > 80 char lines.

Use the das800_ai_get_sample() helper to get the analog input data.

Change the fifo flags into bools and make sure to check for the
fifo overflow while reading the samples. This also fixes the overflow
detection for 12-bit resolutions. In the current code the 'dataPoint'
value has been shifted and masked. This could result in fifo_overflow
being invalidly true.

Remove the need for the 'thisboard' pointer by using the subdevice
'maxdata' to determine the sample size.

The devpriv->forever flag is really a bool. Treat it as such.

Remove the comedi_error() messages. The user will get the error
condition back in the async event. The message is just added noise.
