This is not strictly necessary, but it helps quiet a gcc-4.2 warning (a good
optimizer may optimize this initialization away).

Unionfs: ensure consistent lower inodes types
When looking up a lower object in multiple branches, especially for
directories, ignore any existing entries whose type is different than the

readdir on a non-dir inode).
