[COMMON] g2d: added fence_put() after fence is created

The patch 8fba9cde9b815209e8f8fcd2587c85860b17ad06
hold reference to fence when creating sync_file.

After fence_init and create sync_file, fence reference
has increased twice, so we send the release fence after
decreasing the reference because the user receiving
the release fence expects the fence to increase once.
