ion: use %pK instead of %p which respects kptr_restrict sysctl
Hide kernel pointers from unprivileged users by using %pk format-specifier
instead of %p. This respects the kptr_restrict sysctl setting which is by
default on. So by default %pk will print zeroes as address. echo 1 to
kptr_restrict to print proper kernel address.
