An ino is unsigned so export it as such in /proc/locks.

Hi Jeff,
Ran into this while writing tests to verify i_ino == d_ino == st_ino on
overlayfs. In some configurations (xino=on) overlayfs sets MSB on i_ino,
so /proc/locks reports negative ino values.
BTW, the requirement for (i_ino == d_ino) came from nfsd v3 readdirplus.
Thanks,
Amir.
