Bug Description: deleting attributes when changing password causes server crash
Reviewed by: nhosoi (Thanks!)
Fix Description: From Michal: "The function mod2smod does not check for mod->mod_bvalues being NULL and tries
to dereference it (modutil.c:370). This function happens to be called only by
slapi_mods_get_{first,next}_smod(), which are in turn called only by
check_trivial_words() in pw.c; this is why the crash appears only when checking
password syntax."
I added the same check for the mod_values case - even though the
code says this should never be called, better to be safe than sorry.
Platforms tested: RHEL4
