Allow to configure the number of linear multigrid steps

As the nonlinear smoother is so expensive, doing more than the
canonical single multigrid iteration for the linear correction
problem does not appreciably increase the time per iteration.

In preliminary tests it does decrease the number of iterations
considerably, though.
