Roman Skakun 40ac971eab dma-mapping: handle vmalloc addresses in dma_common_{mmap,get_sgtable} 
xen-swiotlb can use vmalloc backed addresses for dma coherent allocations
and uses the common helpers.  Properly handle them to unbreak Xen on
ARM platforms.

Fixes: 1b65c4e5a9 ("swiotlb-xen: use xen_alloc/free_coherent_pages")
