[PATCH] uml: merge duplicated page table code

There is a lot of code which is duplicated between the 2 and 3 level
implementation, with the only difference that the 3-level implementation is a
bit more generalized (instead of accessing directly pte_t.pte, it uses the
appropriate access macros).

So this code is joined together.

As obvious, a "core code nice cleanup" is not a "stability-friendly patch" so
usual care applies.
