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.
