The d_type field cannot be assumed to be filled. Some filesystems, such as older XFS, will simply report DT_UNKNOWN.
Even if the d_type is filled in, the use of it in the SELinux functions is dubious. If labelling all files in a directory there's no reason to skip things which are not regular files. We merely need to skip "." and "..", which is done by virDirRead() already.

I believe you wanted to remove this hunk instead of changing it, right? "." and ".." are skipped by virDirRead() already.
