iommu/arm-smmu-v3: Avoid open coded arithmetic in memory allocation

Browse source

kmalloc_array()/kcalloc() should be used to avoid potential overflow when
a multiplication is needed to compute the size of the requested memory.

So turn a devm_kzalloc()+explicit size computation into an equivalent
devm_kcalloc().
