do not explicitly pass the permeability to the well model anymore

this information is already part of the EclipseState. The reason why
this should IMO be avoided is that this enforces an implementation
detail (ordering of the permeability matrices) of the simulator on the
well model. If this needs to be done for performance reasons, IMO it
would be smarter to pass an array of matrices instead of passing a raw
array of doubles.  I doubt that this is necessary, though: completing
the full Norne deck takes about 0.25 seconds longer on my machine,
that's substantially less than 0.1% of the total runtime.
