Remove FIXME re: negative maxHeight.

Remove FIXME re: negative maxHeight.

Confirmed that it is possible to construct a page that will produce a
negative maxHeight, as seen in:

fast/block/line-layout/negative-max-height.html

which produces maxHeight of -5.

I'd like to improve the documentation as well but doing so best done with some
in person discussion. In the meantime the FIXME is obsolete. I'll talk with you
or leviw@ in person for more soon.

Also for the record, the FIXME was added in:

which was for https://bugs.webkit.org/show_bug.cgi?id=67202
