ceph: handle racing calls to ceph_init_dentry
The ->lookup() and prepopulate_readdir() callers are working with unhashed dentries, so we don't have to worry. The export.c callers, though, need to initialize something they got back from d_obtain_alias() and are potentially racing with other callers. Make sure we don't return unless the dentry is properly initialized (by us or someone else).
