ceph: silence a checker warning in mdsc_show()
The problem is that if ceph_mdsc_build_path() fails then we set "path" to NULL and the "pathlen" variable is uninitialized. Then we call ceph_mdsc_free_path(path, pathlen) to clean up. Since "path" is NULL, the function is a no-op but Smatch and UBSan still complain that "pathlen" is uninitialized. This patch doesn't change run time, it just silence the warnings.
