Zach Brown d2a15ea506 scoutfs: fix depth-first radix next bit search ...

The radix block next bit search could return a spurious -ENOENT if it
ran out of references in a parent block further down the tree.  It needs
to bubble up to try the next ref in its parent so that it keeps
performing a depth-first search of the entire tree.

This lead to an assertion being tripped in _radix_merge.  Getting an
early -ENOENT caused it to start searching from 0 again.  When it's
iterating over a read-only input it could find the same leaf and try to
clear source bits that were already cleared.
