mesa: add check for NV_texture_barrier in _mesa_TextureBarrierNV()
If an app called glTextureBarrierNV() without checking if the
extension was available, we'd crash with some gallium drivers
in st_TextureBarrier() because the pipe_context::texture_barrier()
pointer was NULL.
Generate GL_INVALID_OPERATION instead.
