staging: most: v4l2-aim: remove unnecessary retval
The function aim_register_videodev() uses the variables 'ret' and
'retval' to represent the same value.
This patch removes 'retval' and replaces it with 'ret'. Further, it
replaces the constant return value '-ENODEV' with the result returned by
function video_register_device() in the event something went wrong.
