RFR: 8266796: Clean up the unnecessary code in the method UnsharedNameTable#fromUtf

[Guoxiong Li]

Hi all,

This little patch cleans up the redundant code. Please see the code below. 


        while (element != null) {
            if (element == null) {
                break;
            }


The `while (element != null)` has already checked the `element`. So the `if (element == null)` is redundant and unnecessary.

Thank you for taking the time to review.

Best Regards,
-- Guoxiong
