Lookup on root was sending "/" as the path.
This will break the basename calculation in
loc_copy and hence lookup on root was failing
if the loc_copy was involved in the stack.
With ctime, a first lookup on root initiates
a metadata self heal because of ctime xattr
not being same on all afr subvolumes. This
results in loc_copy and hence the failure
of lookup.
Fix would be to send path with "." for the root.
