Previous commit made xen-blkback's 'feature_persistent' parameter to
make effect for not only newly created backends but also for every
reconnected backends. This commit makes xen-blkfront's counterpart
parameter to works in same manner and update the document to avoid any
confusion due to inconsistent behavior of same-named parameters.
