8915785acf v2api: fsck: use a temporary mount 
Directly accessing the Nodes does not work properly,
as there is no way to attach a newly LOOKUPped Node
to the tree. This means Path() does not work.

Use an actual mount instead and walk the tree.

77632b7554 getdents_c: read from two threads 
This was an attempt to make the C code more
similar to Go (which also reads from multiple threads).

However, I still could not repro the ENOENT problems.
