mesa: remove 'params' parameter from ctx->Driver.TexParameter()

None of the drivers which implement this hook do anything with the
texture parameter value.  Drivers just look at the pname and set a
dirty flag if needed.

We were doing some ugly casting and type conversion to setup the
argument so that all goes away.
