selftest/mm: test enable_soft_offline behaviors
Add regression and new tests when hugepage has correctable memory errors,
and how userspace wants to deal with it:
* if enable_soft_offline=1, mapped hugepage is soft offlined
* if enable_soft_offline=0, mapped hugepage is intact
Free hugepages case is not explicitly covered by the tests.
Hugepage having corrected memory errors is emulated with
MADV_SOFT_OFFLINE.
