[3.0] Modified the location of ReleaseSurface in NativeRenderSurface

[Model] Tizen 3.0
[Problem] Sometimes aquired ConsumeSurface is NULL
[Cause & Measure] surface release timing between render thread and event thread
[Checking Method] Run gallery application which uses EvasPlugin if it works fine
[Developer] SinJae Lee
