Don't skip invalid functions when looking for var references.

This matches the spec, WebKit and Firefox.

From https://drafts.csswg.org/css-variables/#using-variables:

> If a property contains one or more var() functions, and those functions are
> syntactically valid, the entire property’s grammar must be assumed to be
> valid at parse time. It is only syntax-checked at computed-value time, after
> var() functions have been substituted.
