[igt-dev] [PATCH i-g-t] lib/drmtest: Don't log a warning when drm driver is not loaded

[Zbigniew Kempczyński]

Some drivers left machine with drm driver unloaded. When IGT_DEVICE is
set  __get_card_for_nth_filter() is logging warning each call so we
have confusing duplicates if function is called few times. Lets remove
warning from it and migrate logging resposibility to the caller.
