Christoph Hellwig 66d7780f18 dma-mapping: check pfn validity in dma_common_{mmap,get_sgtable}

Check that the pfn returned from arch_dma_coherent_to_pfn refers to
a valid page and reject the mmap / get_sgtable requests otherwise.

Based on the arm implementation of the mmap and get_sgtable methods.
