Better fix for scan-build warning regarding possible use of NULL in AddRecordHeader. Scan-build considers paths where output is set to NULL, but ssl->spec.kea is corrupted/changed, which could result in output == NULL (even though it should never happen). So added proper NULL check in SendServerKeyExchange on AddHeader to make sure output isn't NULL.
