panfrost: Don't calculate min/max indices on v9

Browse source 
On Valhall, we always* use memory-allocated IDVS, which does not require min/max
indices. As such, we do not want to calculate min/max indices, as this is quite
slow. Skip this step.

* except for blit shaders, which don't use an index buffer anyway.
