[PATCH 5.4 029/203] drm/tegra: Fix ordering of cleanup code

[Greg Kroah-Hartman]

From: Thierry Reding <treding@xxxxxxxxxx>

commit 051172e8c1ceef8749f19faacc1d3bef65d20d8d upstream.

Commit Fixes: b9f8b09ce256 ("drm/tegra: Setup shared IOMMU domain after
initialization") changed the initialization order of the IOMMU related
bits but didn't update the cleanup path accordingly. This asymmetry can
cause failures during error recovery.
