v4->v5:
----
* don't print message on every skey tested (thanks Janosch)
* extend some comments (Thanks Janosch)

v3->v4:
----
* remove useless goto (Thanks Thomas)

v2->v3:
----
* remove some useless variables, style suggestions, improve commit description
  (thanks Janis)
* reverse christmas tree (thanks Claudio)

v1->v2:
----
* As per discussion with Janis and Claudio, remove the actual access check from
  the test. This also allows us to remove the check_pgm_int_code_xfail() patch.
* Typos/Style suggestions (thanks Janis)

Upon migration, we expect storage keys set by the guest to be preserved,
so add a test for it.

We keep 128 pages and set predictable storage keys. Then, we migrate and check
they can be read back.
