staging: comedi: pcl711: use comedi_handle_events()

Browse Source 
Use comedi_handle_events() to automatically (*cancel) the async command
for an end-of-acquisition or if an error/overflow occurs.

The pcl711_ai_set_mode() call when the end-of-acquisition is detected
can then be removed. The (*cancel) does the same thing.
