[PATCH libdrm] tests: fix memory leak issue

[Inki Dae]

Fixed memory leak issue to drmModeRes object.

This object was allocated by drmModeGetResources function
but not freed when device->screens failed.

So this patch frees the drmModeRes object when device->screens failed
by calling drmModeFreeResources function.
