ACPI/IORT: Fix the error return code in iort_add_smmu_platform_device()

The function iort_add_smmu_platform_device() accidentally returns 0
(ie PTR_ERR(pdev) where pdev == NULL) if platform_device_alloc() fails;
fix the bug by returning a proper error value.

Fixes: 846f0e9e74a0 ("ACPI/IORT: Add support for ARM SMMU platform devices creation")
