iommu/arm-smmu: Fix uninitilized variable warning
Some unrelated changes in the iommu code caused a new warning to
appear in the arm-smmu driver:
CC drivers/iommu/arm-smmu.o
drivers/iommu/arm-smmu.c: In function 'arm_smmu_add_device':
drivers/iommu/arm-smmu.c:1441:2: warning: 'smmu' may be used uninitialized in this function [-Wmaybe-uninitialized]
arm_smmu_rpm_put(smmu);
^~~~~~~~~~~~~~~~~~~~~~
The warning is a false positive, but initialize the variable to NULL
to get rid of it.
