staging: comedi: ni_tiocmd: change mistaken use of start_src for start_arg

[ Upstream commit 1fd24a4702d2af0ea4d5845126cf57d4d1796216 ]

This fixes a bug in function ni_tio_input_inttrig().  The trigger number
should be compared to cmd->start_arg, not cmd->start_src.

Fixes: 6a760394d7eb ("staging: comedi: ni_tiocmd: clarify the cmd->start_arg validation and use")
