drm/tegra: Fix ordering of cleanup code

Browse Source 
commit 051172e8c1 upstream.

Commit Fixes: b9f8b09ce2 ("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.
