xen: gntdev: fix build warning
addr is actually a virtual address so use an unsigned long. Fixes: CC drivers/xen/gntdev.o drivers/xen/gntdev.c: In function 'map_grant_pages': drivers/xen/gntdev.c:268: warning: cast from pointer to integer of different size Reduce the scope of the variable at the same time.
