tgsi: don't fail on unknown property

They should mostly be fine, as long the shader compiles. The reported
error should be enough to diagnose something going wrong in case of
failure.

This should help avoiding temporary regressions when new properties are
introduced in mesa.git before they are either handled or filtered out by
virgl, as was the case with commit fbe6e92899.
