[PATCH v3 0/2] Fix persistent grants negotiation with a behavior change

[SeongJae Park <sj@xxxxxxxxxx>]

The first patch of this patchset fixes 'feature_persistent' parameter
handling in 'blkback' to respect the frontend's persistent grants
support always.  The fix makes a behavioral change, so the second patch
makes the counterpart of 'blkfront' to consistently follow the behavior
change.

- Keep the behavioral change of v1
- Update blkfront's counterpart to follow the changed behavior
- Update documents for the changed behavior
