Commit 669c9215afea ("drm/atomic: Make async plane update checks work as intended, v2.") forced planes to always be tracked, but forgot to explicitly get the crtc commit from the new crtc when available.
This broke plane commit tracking, and caused kms_atomic_transitions to randomly fail with -EBUSY.
