cluster/dht: pathinfo xattr changes for directories
Since directories have presence on all subvolumes there is no definite meaning of ->hashed_subvol or ->cached_subvol. getxattr() code path chooses ->cached_subvol for pathinfo extended attribute. While this makes sense of files, it makes less sense for directories. Further if a hashed or a cached subvolume is down, and there's a getxattr request for a directory, we return with an errno. This patch changes pathinfo extended attribute contents by aggregating information from all subvolumes that are up.
