st/mesa: release tgsi tokens for shader states

Since we are using st_common_variant while creating variant for vertext
program, we can release tokens created in st_create_vp_variant which
are already stored in respective states.
This fix memory leak found with piglit tests

Fixes bc99b22a305b ('st/mesa: use a separate VS variant for the draw module')
