Artem Chernyshev d5fe884ce2 iommu: sprd: Avoid NULL deref in sprd_iommu_hw_en 
[ Upstream commit 630482ee0653decf9e2482ac6181897eb6cde5b8 ]

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.

Fixes: 9afea57384d4 ("iommu/sprd: Release dma buffer to avoid memory leak")
