[PATCH 2/2] xen: p2m: Use the correct type for p2m page

[Stefan Bader]

In "xen: p2m: correctly initialize partial p2m leave" I introduced new
compiler warnings by using unsigned long ** instead of unsigned long *
for the 3rd level tree structure. Due to the nature of pointers and long
this works practically but it should be done right.
