[OpenJDK 2D-Dev] [9]: RFR JDK-8139803, , Fix for 8132985 breaks OpenJDK build on windows

[prasanta sadhukhan]

Hi All,

Please review a small fix for jdk9

Bug: https://bugs.openjdk.java.net/browse/JDK-8139803
webrev: http://cr.openjdk.java.net/~psadhukhan/8139803/webrev/

Fix for 8132985: Crash in freetypescaler.c due to double free was 
breaking openjdk build on windows
as an used variable was not removed and since warnings are treated as 
errors, it results in build error.

Regards
Prasanta
