nir: Fix logic that ends combine barrier sequence

The combination must stop when we see a scoped barrier that have
execution scope, i.e. it has control barrier behavior.  The code was
mistakenly looking at the wrong scope.

Fixes: 345b5847b42 ("nir: Replace the scoped_memory barrier by a 
scoped_barrier")
