freedreno/ir3: fix missing (ss) in dummy bary.f case

Browse source 
In case we need to insert a dummy bary.f for the (ei) flag, it also
needs (ss) so we don't release varying storage to the next VS wave
before the ldlv completed.  Fixes random failures in:

dEQP-GLES3.functional.transform_feedback.random.interleaved.lines.*
