xen/xenbus: Fix granting of vmalloc'd memory
[ Upstream commit d742db70033c745e410523e00522ee0cfe2aa416 ]
On some architectures (like ARM), virt_to_gfn cannot be used for
vmalloc'd memory because of its reliance on virt_to_phys. This patch
introduces a check for vmalloc'd addresses and obtains the PFN using
vmalloc_to_pfn in that case.
