netlabel: Remove unneeded in-kernel API functions
After some discussions with the Smack folks, well just Casey, I now have a
better idea of what Smack wants out of NetLabel in the future so I think it
is now safe to do some API "pruning". If another LSM comes along that
needs this functionality we can always add it back in, but I don't see any
LSMs on the horizon which might make use of these functions.
Thanks to Rami Rosen who suggested removing netlbl_cfg_cipsov4_del() back
in February 2008.
