perf report: Remove unnecessary check in annotate_browser_write()

In annotate_browser_write(),

        if (dl->offset != -1 && percent_max != 0.0) {
                if (percent_max != 0.0) {
			...
                }
                ...
        }

The second check of (percent_max != 0.0) is not necessary, remove it.
