This fixes one build error introduced in sparc with the patch of Oct 30,
resent Nov 4 "[patch 3/5] atomic: atomic_inc_not_zero" I still can't get
sparc to build, but at least it gets further after I remove this line. 
Apparently, this change was agreed to by Andrew and Nick on Nov 14, but
everyone thought someone else was doing it.
