drm/i915/fbc: Consult hw.crtc instead of uapi.crtc
plane_state->uapi.crtc is not what we want to be looking at. If bigjoiner is used hw.crtc is what tells us what crtc the plane is supposedly using. Not an actual problem on current hardware as the only FBC capable pipe (A) can't be a bigjoiner slave and thus uapi.crtc==hw.crtc always here. But when we get more FBC instances this will become actually important.
