[PATCH v2 15/25] staging: comedi: addi_apci_2032: use comedi_handle_events()

[H Hartley Sweeten]

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

Also, comedi_handle_events() does nothing if no events are set so the
local variable 'do_event' can be removed.
