[git commit future 1/1] lckpwdf.c: add back lost return

[Khem Raj]

commit: http://git.uclibc.org/uClibc/commit/?id=6045a6be0a172206a7068f8e086c7d2967bee505
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/future

2 earlier (2006 and 2009) commits killed the proper return: -1 for failure, 0 on success
