ovl: use a private non-persistent ino pool
There is no reason to deplete the system's global get_next_ino() pool for
overlay non-persistent inode numbers and there is no reason at all to
allocate non-persistent inode numbers for non-directories.
For non-directories, it is much better to leave i_ino the same as real
i_ino, to be consistent with st_ino/d_ino.
