RFR: 8334670: SSLSocketOutputRecord buffer miscalculation

[Anthony Scarpino]

Hi,

I need a review to change the a fragment buffer size miscalculation error.   This appears when there are large handshake messages and hasn't been observed during application data.  This was found during testing of the NewSessionTicket change in [JDK-8328608](https://bugs.openjdk.org/browse/JDK-8328608).  There is no regression test as the failure hasn't shown to fail every time. 

thanks

Tony
