panfrost: don't try to emit varying shader stats on v12+

Browse source 
On v12+, IDVS no longer has separate position and varying variants, so
we only need to emit stats for one binary. Attempting to emit stats for
the nonexistent varying shader breaks shader-db.

Fixes: 7819b103fa ("pan/bi: Add support for IDVS2 on Avalon")
