Subject: drm/tegra: dc: Free syncpoint on errors
Git-commit: fd5ec0dc34dafa6c5bb46770ca283ae90a4db3c7
Patch-mainline: v4.18-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

If an error happens during display controller initialization, the host1x
syncpoint previously requested would be leaked. Properly clean up the
syncpoint along with the other resources.
