prevent error to be shouted when the .probe() returns -ENODEV

Seen on the second input node of the Roccat Kone XTD:
"ratbag error: ROCCAT Kone XTD: driver specified in hwdb not found: roccat

With the new hwdb matching, we should not try any other driver not having
the right id, so simplify the for loop to find the driver only.

Fixes #32
