drm/radeon: Remove test for !screen_base in fbdev probing

Browse Source 
The screen_base field comes from the fbdev BO and contains the fbdev
framebuffer base address. We get the BO memory via radeon_bo_kmap(),
which already reports the error -ENOMEM if the buffer could not be
mapped. So remove the later test for screen_base, which will never
be NULL at this point.
