NFSv4 client might instantiate the distinct vnodes which have the same inode number, since single v4 export can be combined from several filesystems on the server. For instance, a case when the nested server mount point is exactly one directory below the top of the export, causes directory and its parent to have the same inode number 2. The vop_stdvptocnp() algorithm then returns "." as the name of the lower directory. Filtering out the "." entry with ENOENT works around this behaviour, the error forces getcwd(3) to fall back to usermode implementation, which compares both st_dev and st_ino.
