Revert "Fix/Workaround T44662: Freestyle gives no visual output when the Save Buffers option is enabled"

This reverts commit ab417f31f403d74a76fb51fbd6e2aa3f706e15f1.

This workaround caused serious memory corruption issues which is not really acceptable
for the release. We'll be likely sticking to a more limited release when using freestyle
with saved buffers for until proper solution is implemented.
