xen/p2m/debugfs: Fix potential pointer exception.
We could be referencing the last + 1 element of level_name[] array which would cause a pointer exception, because of the initial setup of lvl=4. [v1: No need to do this for type_name, pointed out by Ian Campbell] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
