KVM: selftests: Stop passing a memslot to nested_map_memslot()
On x86, KVM selftests use memslot 0 for all the default regions used by
the test infrastructure. This is an implementation detail.
nested_map_memslot() is currently used to map the default regions by
explicitly passing slot 0, which leaks the library implementation into
the caller.
Rename the function to a very verbose
nested_identity_map_default_memslots() to reflect what it actually does.
Add an assertion that only memslot 0 is being used so that the
implementation does not change from under us.
No functional change intended.
