Zach Brown ecbf59d130 scoutfs: use migration key instead of bits ...

The bit tracking code was a bit much (HA).  It introduced a lot of
complexity just to provide a way to migrate blocks from the old
half of the ring into the current half of the ring.

We can get rid of a ton of code and potential for bugs if we simply
store a persistent migration key in the super and use it to
sweep the tree looking for old blocks to dirty.  A simple tree walk
that dirties and returns the next key is all we need.
