move_view: fix view->offset overflow bug

Reproducable by opening the tree view, then maximizing the blob view,
move up, and then closing the blob view, causing the view->offset to
have "wrapped around" and nothing to be displayed in the tree view.

The invalid update of view->offset only happend when moving
non-displayed views.  Instead use the checked scroll_steps variable
instead of the steps variable.  Add a guarding assert after the update.
