isisd: fix two 'no X' commands

for some reason, when issuing a 'no metric-style' command we were
setting the metric-style to narrow, even though the default is
actually wide. Use NULL to avoid similar problems in the future.

Likewise, the 'no is-type' command was still trying to implement
the old logic of applying a different default for the first area.
In practice this had no effect because the value would now be the
same in both cases, but it's better to remove useless code anyway.
