* 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 being 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 and the respective access restrictions are in place when
the access key in the PSW doesn't match.
