[PATCH] resource: fix printk() of resource_size_t

[H . Peter Anvin]

Impact: crash on 32-bit platforms, warnings on 64-bit platforms

When printk'ing resource_size_t, we have to explicitly cast them to
unsigned long long in order to be safe on all platforms.  We must not use
%z since that applies to size_t, which is frequently not the same type
as resource_size_t.
