staging: comedi: ni_mio_common: tidy up AO trigger selection

The AO subdevice (*cancel), ni_ao_reset(), always sets the private
data 'ao_trigger_select' to 0. So when a command is started the
'trigsel' value in ni_ao_cmd_set_trigger() will always start as 0.
Remove the unnecessary member from the private data.

The (*do_cmdtest) validates that the cmd->start_src will only be
TRIG_INT or TRIG_EXT. Refactor ni_ao_cmd_set_trigger() and remove
the BUG() which can never occur.
