opendir_cb: use attributes from the nested mount in opendir 

When opendir_cb encounters an entry that refers to a nested mount, then
replace the attributes with those attributes we collected for this export
during the mount and return those instead.

This makes traversing a director that crosses into a different filesystem
on the server transparent to the client.
