[rsbac] umount nfs on laptop

[Jens Kasten]

Hi list,

I do mount my portage tree and some others with nfs to my laptop.
Now for example when I close the Laptop the system goes to suspend.
After open the Laptop again the mounted directories can't access
anymore.
I get this: 

rsbac_umount: removed primary mount for device 00:20, inheritance
broken!

As workaround would maybe help befor going to suspend unmount the
directories but this solve not the similar problem when wlan is
unexpected off.
