You can generically prevent anything like this by altering HOME to the
resolved path in your .zshrc:

if [[ $PWD = $HOME(|/*) ]]; then
  newdir=${PWD##$HOME}
  HOME=$(cd $HOME && pwd -r || print $HOME)
  cd $HOME${newdir}
  unset newdir
else
  HOME=$(cd $HOME && pwd -r || print $HOME)
fi

This produces HOME=/net/server/share/home/luthien in your case.
That's a general case --- you can shorten the code if you assume a
particular form for $HOME before and after resolution.

If you want to keep inside the symbolic link, since it's mc that's
resolving the link and presenting zsh with it, and zsh can't tell if
there's a symbolic link pointing to the current directory, it looks like
you need to handle this case specially in mc somehow.  Obviously you can
replace /net/server/share/home with /home in the directory before changing
to it.

cd ${$(<"$MC")##/net/server/share}

What more are you looking for?
