librbd: the first post-migration snapshot isn't always dirty

Currently, the first post-migration snapshot is always marked EXISTS
(i.e. dirty).  This is wrong, because the data can be inherited from
a pre-migration snapshot, handled by deep copy.

Mark all post-migration snapshots EXISTS_CLEAN in this case.
