Patch to either dublicate or reuse an existing crtc state that might pervent
use-after-free error in race condition

I wasn't able to reproduce the issue, but could you please try applying this
patch and seeing if does any difference?

Also could add a dmesg log with drm.debug=0x6 to see whats the chain of events
that caused the issue
