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.
Fixes: 964fff7491e4 ("ceph: use ceph_mdsc_build_path instead of clone_dentry_name")
