    nss_winbind: When returning NSS_UNAVAIL, squash errno to ENOENT
    
    According to the GNU libc nss guide, we should always set
    errno to ENOENT when returning NSS_UNAVAIL.
    
    
http://www.gnu.org/software/libtool/manual/libc/NSS-Modules-Interface.html#NSS-Modules-Interface
    
    At least the MQ Series message queing service that runs
    on WebSphere will fail if you return any other errno in this case.
