tty/vt: consolemap: make con_set_unimap() more readable

The indentation was completely broken in con_set_unimap(). Reorder the
code using 'if (!cond) continue;'s so that the code makes sense. Not
that it is perfect now, but it can be followed at least. More cleanup to
come. And remove all those useless whitespaces at the EOLs too.
