drm/i915: set "ret" correctly on error paths

Browse source

If "crtc" is NULL, then my static checker complains that "ret" isn't
initialized on that path.  It doesn't really cause a problem unless
"ret" is somehow set to -EDEADLK which is not likely.

Chris Wilson also noticed another error path where "ret" isn't set
correctly.
