Fix crash in KCM Samba

This patch should fix the crash when saving the Samba settings.

I am, however, not sure if just skipping the "setValue" call is the right way to do this.

Maybe the function should be called with a default/empty value, or with parameter "defaultValue" set to true.

No, bug 180392 crashes in fileshare_propsdlgplugin.so, while this one crashed in kcm_kcmsambaconf.so.
