drm/i915: clean up pipe's ddb usage in intel_crtc_disable_noatomic()
Update the ddb tracking information when we disable a pipe
during sanitization. Avoids leaving stale junk in the states.
Currently this doesn't do anything as we haven't read out this
state yet when we do the sanitization, but that will change soon.
