If any subvolume is down, and a layout is re-written and hash
values change, entry names in the downed subvol can be reused
in the other subvol which got the same hash range. when the
downed subvol is brought back up, duplicate entried might appear
Also separated handling of ENOSPC and ENOTCONN error.
