xen/netback: Pass (void *) to virt_to_page()
virt_to_page() takes a virtual address as argument but the driver passes an unsigned long, which works because the target platform(s) uses polymorphic macros to calculate the page. Since many architectures implement virt_to_pfn() as a macro, this function becomes polymorphic and accepts both a (unsigned long) and a (void *). Fix this up by an explicit (void *) cast.
