drm/i915: Remove obsolete code from intelfb_alloc()

Clean up after 0c82312f3f ("drm/i915: Pin the ifbdev for the
info->system_base GGTT mmapping"):

At each of the remaining "goto out" in intelfb_alloc(), fb can only be
either an ERR_PTR or NULL, so the call to drm_framebuffer_unreference()
is now obsolete.
