atm nicstar: Removal of debug code containing deprecated calls to cli()/sti()

Code within NS_DEBUG_SPINLOCKS contained deprecated cli()/sti()
function calls.  NS_DEBUG_SPINLOCKS and the associated code seems to
be of little use these days so the strategy of removing this code
rather then updating it to use spinlocks has been taken.
