ceph: fix ceph_mdsc_build_path to not stop on first component
When ceph_mdsc_build_path is handed a positive dentry, it will return a zero-length path string with the base set to that dentry. This is not what we want. Always include at least one path component in the string. ceph_mdsc_build_path has behaved this way for a long time but it didn't matter until recent d_name handling rework.
