This patchset fixes misuse of the 'feature-persistent' advertisement
semantic (patches 1 and 2), and the wrong timing of the
'feature_persistent' value caching, which made persistent grants feature
always disabled.

that the persistent grants feature becomes always disabled.
This commit fixes the issue by making the blkfront does parmeter caching
just before the advertisement.
