RFR: 8259385: Cleanup unused assignment [v2]

[Xue-Lei Andrew Fan]

> In the SunJSSE provider implementation, there are a few cases that the assigned value is never used.  For example:
>   int i = 0;
>   i = Byte.toUnsignedInt(buf.get());
> could be simplified as
> `    int i = Byte.toUnsignedInt(buf.get());`
> 
> Code cleanup, no new regression test.
