Artem Chernyshev 8c79ceb4ec iommu: sprd: Avoid NULL deref in sprd_iommu_hw_en
[ Upstream commit 630482ee06 ]

In sprd_iommu_cleanup() before calling function sprd_iommu_hw_en()
dom->sdev is equal to NULL, which leads to null dereference.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
