pgsql: psql: Fix CREATE INDEX tab completion

psql: Fix CREATE INDEX tab completion

The previous code supported a syntax like CREATE INDEX name
CONCURRENTLY, which never existed.  Mistake introduced in commit
37ec19a15ce452ee94f32ebc3d6a9a45868e82fd.  Remove the addition of
CONCURRENTLY at that point.
