iommu/arm-smmu: Fix error checking for ASID and VMID allocation The bitmap allocator returns an int, which is one of the standard negative values on failure. Rather than assigning this straight to a u16 (like we do for the ASID and VMID callers), which means that we won't detect failure correctly, use an int for the purposes of error checking.
