Subject: [PATCH] staging: comedi: ni_at_a2150: use cfc_handle_events()

Use the comedi_fc helper function to automatically call the subdevice
(*cancel) function when needed and call comedi_event().

Also, remove the clearing of the events, comedi_event() does that.

In the Kconfig, COMEDI_NI_AT_A2150 already selects COMEDI_FC.
