x86: fix dma_mapping_error for 32bit x86, cleanup
This removes ifdef CONFIG_X86_64 in dma_mapping_error(): 1) Xen people plan to use swiotlb on X86_32 for Dom0 support. swiotlb uses ops->mapping_error so X86_32 also needs to check ops->mapping_error. 2) Removing #ifdef hack is almost always a good thing.
