Subject: drm/msm: Mark the crtc->state->event consumed
Git-commit: 78b32d49c49f7162f9ab5884a1b7228f6bfa2632
Patch-mainline: v4.17-rc3
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Don't leave the event != NULL once it's consumed, this is used a signal
to the atomic helpers that the event will be handled by the driver.

Changes in v2:
- None
Changes in v3:
- Rebased on Archit's private_obj set
Changes in v4:
- None
