Don't check if the requested display mode is in the mode list - just ask the

graphics add-on if it can handle it.
This fixes setting the screen resolution natively. Unfortunately, that's not
all (the input_server still constraints the cursor position to the previous
resolution...). Also, there is apparently no B_SCREEN_CHANGED sent.
