ceph: fix memory leaks in ceph_mdsc_build_path()

Browse source

commit 040d159a45 upstream.

Add __putname() calls to error code paths that did not free the "path"
pointer obtained by __getname().  If ownership of this pointer is not
passed to the caller via path_info.path, the function must free it
before returning.
