libvhost-user: fix -Werror=format= on ppc64

That should fix the following warning:

/home/pm215/qemu/contrib/libvhost-user/libvhost-user.c: In function
‘vu_set_mem_table_exec_postcopy’:
/home/pm215/qemu/contrib/libvhost-user/libvhost-user.c:666:9: error:
format ‘%llx’ expects argument of type ‘long long unsigned int’, but
argument 5 has type ‘__u64’ [-Werror=format=]
         DPRINT("%s: region %d: Registered userfault for %llx + %llx\n",
         ^
/home/pm215/qemu/contrib/libvhost-user/libvhost-user.c:666:9: error:
