Change the error log when populateViewport

Currently, we are logging an error when a display does not
support input device matching.
(ex: a virtual display without TOUCH_VIRTUAL)
But that's not a really an error.

Convert it to a normal log instead.

Test: Create a virtual display without touch. Check logcat.
