Unionfs: initialize path_save variable
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

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

lower file system is being unmounted with MNT_FORCE or MNT_DETACH.
