Unionfs: initialize path_save variable
This is not strictly necessary, but it helps quiet a gcc-4.2 warning (a good

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
type of the first found object (otherwise we'll be trying to, say, call
readdir on a non-dir inode).
