Fix GridTrackSize::operator==
https://bugs.webkit.org/show_bug.cgi?id=112501

Reviewed by Eric Seidel.

Source/WebCore:

There was a missing "other." in the function.

This was found by experimenting with a potential new Clang warning.

Test: fast/css-grid-layout/grid-dynamic-updates-relayout.html

* rendering/style/GridTrackSize.h:
(WebCore::GridTrackSize::operator==):
