The variable res is being assigned a value that isn't being read
later. The assignment is redundant and can be removed.
Cleans up clang scan warning:
drivers/iommu/arm/arm-smmu/arm-smmu.c:2109:10: warning: Although the
value stored to 'res' is used in the enclosing expression, the value
is never actually read from 'res' [deadcode.DeadStores]
