drm/i915: Fix memory leak in intel_dsi_init() error path
intel_dsi_init() bails out without freeing the memory 'intel_dsi' and 'intel_connector' point to. Simply bail out before allocating memory. Picked up by Coverity - CID 1222750. Signed-off-by: Christoph Jaeger <christophjaeger@linux.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
