Use cfc_handler_events() to automatically (*cancel) the async command for
an end-of-acquisition or if an error/overflow occurs.
The s626_mc_disable() call when the end-of-acquisition is detected can then
be removed. The (*cancel) does the same thing.
For aesthetics, also remove the 'finished' local variable and just return
the ai_cmd_running state.
