softwrap: initialize the 'extrarows' value for the magic line correctly

The make_new_node() function initializes 'extrarows' to a bad value
on purpose, to catch cases like this one where it doesn't get updated
properly.

This fixes https://savannah.gnu.org/bugs/?58890.
Reported-by: Jerry Kindall <kindall@gmail.com>

Bug existed since version 5.0, since the indicator was introduced.
